How to Fix Windows 11 Start Menu Not Working (2026 Deep Guide)

Quick answer

Most Start menu failures are fixed in the first three steps, and none of them touches your files.

✅

The short version

Press Ctrl + Shift + Esc to open Task Manager. Restart Windows Explorer, then end the Start and Search processes. If that does not help, restart the PC with Restart (not Shut down), install updates, and re-register the Start packages from an administrator PowerShell window. On Windows 11 24H2 or 25H2, also register the three XAML packages.

Restart Explorer and the Start processes from Task Manager (Fix 1).
Do a full restart and turn off Fast Startup (Fix 2).
Test the Windows key against the mouse click (Fix 3).
Install updates or remove the one that broke Start (Fix 4).
Register the Start and XAML packages with PowerShell (Fix 7 and Fix 9).
Test a new user account, then repair or reinstall Windows (Fix 11, Fix 14).

⚠️

Before you run any command

Commands here run with administrator rights. They are safe for the tasks described, but copy them exactly, read what each one does, and keep a backup of important files before the last resort fixes.

Diagnose your Start menu in 30 seconds

Answer up to three questions. You get the fixes that match your situation, in the right order.

Start menu diagnosis

Skip ahead if this is you:

Open your tools without the Start menu

You do not need Start to repair Start. Use these shortcuts and Run commands. Press Windows + R, type the command and press Enter.

Tool	Keyboard shortcut	Or type in Run
Task Manager	Ctrl + Shift + Esc	taskmgr
Run box	Windows + R	Opens the box itself
Settings	Windows + I	ms-settings:
Windows Update	Windows + I, then Windows Update	ms-settings:windowsupdate
Terminal (Admin)	Windows + X, then A	Task Manager → File → Run new task → powershell (tick administrative rights)
Installed updates	None	appwiz.cpl, then View installed updates
Services	None	services.msc
System Restore	None	rstrui
Event Viewer	None	eventvwr.msc
Recovery menu	Hold Shift and click Restart on the sign-in screen	Troubleshoot → Advanced options

💡

If the Windows key is dead

Press Ctrl + Esc, which also opens Start. If keyboard shortcuts fail altogether, press Ctrl + Alt + Del and choose Task Manager, then use File → Run new task to start any tool by name.

Decoders: symptoms and the parts behind them

The first table matches what you see to the likely cause. The second names the parts Start depends on, so the names in Task Manager make sense.

What you see

What you see	What it usually means	Go to
Start does nothing when clicked, and the Windows key does nothing	The Start process crashed or its package registration is damaged	Fix 1, Fix 7, Fix 9
The mouse click works but the Windows key does not	A key lock, keyboard software, a remap or a policy	Fix 3, Fix 12
Windows + R and Windows + X work, but Start does not	The Start host process or its packages	Fix 1, Fix 7, Fix 8, Fix 9
The taskbar is frozen and nothing responds	Explorer is hung, the PC is overloaded or an update broke it	Fix 1, Fix 2, Fix 4, Fix 5
Critical Error: Your Start menu isn't working	Damaged registration, profile or update	Fix 9, Fix 7, Fix 11, Fix 5
Start opens blank or white	Damaged Start layout file or a package problem	Fix 8, Fix 7, Fix 1
Start opens, but search shows nothing or keeps loading	The search service, index or web suggestions	Fix 6, Fix 1
Start works for one user but not another	A damaged profile or a policy for that user	Fix 11, Fix 12
Fails only right after sign-in or startup	Fast Startup, startup load or a shell hook	Fix 2, Fix 10, Fix 9
Started right after an update	A bad update or unregistered shell packages	Fix 4, Fix 9, Fix 13
Taskbar and Settings also fail on 24H2 or 25H2	XAML packages not registered after provisioning	Fix 9

The parts behind Start

Part	What it does	When it fails	Go to
explorer.exe (Windows Explorer)	Draws the taskbar, desktop, File Explorer and the Start button	Taskbar vanishes or freezes	Fix 1, Fix 2
StartMenuExperienceHost.exe	Draws the Start panel	Start does not open, or flashes and closes	Fix 1, Fix 7, Fix 8
SearchHost.exe	Shows the search box and results in Start	Search is blank or stuck	Fix 6, Fix 1
Windows Search service (WSearch)	Builds and reads the search index	No results, or results are slow	Fix 6
MicrosoftWindows.Client.CBS and XAML packages	Hold the code that Start, the taskbar and Settings are built from	Start, Settings and taskbar fail together	Fix 7, Fix 9
start2.bin in your profile	Stores your pinned layout	Blank Start or missing pins	Fix 8

Read the crash in Event Viewer

Press Windows + R, type eventvwr.msc and press Enter.
Open Windows Logs → Application and click Filter Current Log, then choose Error.
Look for entries with Application Error or Application Hang that name StartMenuExperienceHost.exe, SearchHost.exe or explorer.exe, near the time Start failed.
The faulting module name tells you what to look at. A name that belongs to a program you installed points to that program (Fix 10). Windows names point to repairs (Fix 5, 7 and 9).

Before you start

Two minutes of preparation prevents most surprises.

I know my Windows 11 version. Press Windows + R, type winver and press Enter.I saved my open work and backed up important files.I know whether this PC is managed by work or school.I remember any Start or taskbar tweak tools I installed.I know my Microsoft account password and my BitLocker key in case of a repair or reset.I can open Task Manager with Ctrl + Shift + Esc.

Tried 0/15

Quick resets

Five-minute fixes that do not change your system.

1Restart Windows Explorer and the Start processesSafeAbout 5 minutesThe fastest fix, and it clears most hangs

Use this when

Start does not respond when you click it or press the Windows key, it opens and closes at once, or the taskbar feels frozen.

Why it works

The taskbar and the Start button live in Windows Explorer, and the Start panel is drawn by a separate process called StartMenuExperienceHost. If either hangs, Start looks dead. Restarting them reloads the shell without a full reboot and does not touch your files.

Steps

Press Ctrl + Shift + Esc to open Task Manager. If it opens small, click More details.
On the Processes tab, right-click Windows Explorer and choose Restart. The taskbar disappears for a moment and returns.
Find Start (StartMenuExperienceHost.exe) and Search (SearchHost.exe) in the list, or on the Details tab. Right-click each and choose End task. Windows starts them again the next time you open Start or Search.
If Explorer is missing, or the screen is blank, choose File → Run new task, type explorer.exe and click OK.
Click Start and press the Windows key. Test both.

Command Prompt, started from Task Manager → Run new task → cmd

taskkill /f /im StartMenuExperienceHost.exe
taskkill /f /im SearchHost.exe
taskkill /f /im explorer.exe
start explorer.exe

taskkill /f /im: force-closes the named process
start explorer.exe: starts the taskbar and desktop again

💡

Screen went blank?

That is normal when Explorer is closed. Press Ctrl + Shift + Esc, choose File → Run new task and run explorer.exe to bring it back.

2Do a full restart, wait for startup and turn off Fast StartupCautionAbout 10 minutesFixes Start that fails right after sign-in

Use this when

Start works after a while but not right after you sign in, or it fails only after a normal Shut down.

Why it works

Windows 11 does a hybrid shutdown (Fast Startup) by default, which keeps part of the system state. Start can load into a half-ready shell. Many startup apps also slow the shell down for a couple of minutes after sign-in. A real restart and fewer startup apps give Start a clean start.

Steps

Use Restart, not Shut down. Restart always reloads Windows fully.
After you sign in, wait 2 to 3 minutes before you judge Start, because startup apps are still loading.
Turn off Fast Startup: press Windows + R, type powercfg.cpl, click Choose what the power buttons do → Change settings that are currently unavailable, untick Turn on fast startup (recommended) and click Save changes.
Open Task Manager → Startup apps. Right-click apps with High startup impact that you do not need right away (updaters, launchers, chat apps) and choose Disable.
Check free space on drive C. Windows needs several gigabytes free to work properly. Free some if the drive is nearly full.
As a last quick test, press Ctrl + Alt + Del, choose Sign out, then sign in again.

3Test the Windows key, your keyboard and the Start buttonSafeAbout 10 minutesIs it Start, or just the key?

Use this when

Clicking the Start button works but the Windows key does not, or the other way round.

Why it works

A locked Windows key, keyboard software, a remapped key or a policy can disable the key while Start itself is fine. Testing both ways splits a keyboard problem from a Start problem.

Steps

Click the Start button with the mouse. Then try Ctrl + Esc, which also opens Start. Then press the Windows key.
Mouse works, key does not: look for a Win lock or Game mode key on your keyboard, often a key with a crossed-out Windows logo, or an Fn + Windows combination. Check Fn Lock too.
Close or check keyboard software such as Logitech G HUB, Razer Synapse or Corsair iCUE. Many have a game mode that disables the Windows key.
If you use PowerToys, open Keyboard Manager and check that the Windows key is not remapped.
Plug in a different keyboard, or use the on-screen keyboard, to see if the problem follows the keyboard.
Run the two read-only checks below to see if a policy or key map disables the Windows key.

Command Prompt (read-only)

reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer" /v NoWinKeys
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Keyboard Layout" /v "Scancode Map"

NoWinKeys: a value of 1 disables Windows key shortcuts
Scancode Map: if this exists, a program has remapped or disabled keys

💡

Not found is a good answer

If a query says it cannot find the value, no policy or key map is blocking the key. The cause is the keyboard, its software or Start.

Updates and system health

Rule out a bad update, damaged files and a broken search service.

4Install updates, or remove the update that broke StartCautionAbout 20 to 40 minutesWhen it began after an update

Use this when

Start stopped after a Windows update, or your PC is behind on updates.

Why it works

Cumulative updates can break shell components, and later updates often fix them. Installing the newest update fixes known problems. Removing the one that started the problem shows whether it is the cause.

Steps

Open Settings without Start: press Windows + I, or press Windows + R and type ms-settings:windowsupdate.
Click Check for updates, install everything, and restart. Also open Advanced options → Optional updates for display and chipset drivers.
To remove an update: open Windows Update → Update history → Uninstall updates, or press Windows + R, run appwiz.cpl and click View installed updates. Choose the most recent update from around the time the problem began and click Uninstall.
If Settings will not open, hold Shift and click Restart on the sign-in screen, then choose Troubleshoot → Advanced options → Uninstall Updates → Uninstall latest quality update.
Pause updates for a week after removing one, so it does not reinstall at once.
Check Microsoft's Windows release health page for known issues with your version.

Command Prompt (Admin), optional

wusa /uninstall /kb:NNNNNNN

/kb:NNNNNNN: replace NNNNNNN with the KB number you want to remove. Some cumulative updates cannot be removed this way

⚠️

Known issue since mid-2025

Microsoft has confirmed that after some cumulative updates, Windows 11 24H2 and 25H2 can fail to register shell packages. Start, Settings, the taskbar and Search can then stop working. If this matches your case, go to Fix 9.

5Repair Windows system files with DISM and SFCSafeAbout 20 to 40 minutesFixes corrupted Windows files

Use this when

Start fails along with other problems, such as Settings not opening, random crashes or error messages in Windows.

Why it works

DISM repairs the Windows component store, which holds the clean copies of system files. SFC then replaces any damaged protected files from that store. Your personal files are not touched.

Steps

Press Ctrl + Shift + Esc to open Task Manager, choose File → Run new task, type powershell, tick Create this task with administrative privileges and click OK.
Run DISM /Online /Cleanup-Image /RestoreHealth first. It can sit at a percentage for a long time. Let it finish.
Then run sfc /scannow. Wait for Verification 100% complete.
Restart the PC and test Start.
If SFC says it found files it could not fix, run DISM again, then SFC again. The details are in the file C:\Windows\Logs\CBS\CBS.log.

PowerShell (Administrator)

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

DISM … /RestoreHealth: repairs the Windows component store using Windows Update
sfc /scannow: checks protected system files and replaces damaged ones

6Fix Start menu search and the Windows Search serviceCautionAbout 15 minutesStart opens, but search is blank or stuck

Use this when

Start opens, but typing finds nothing, shows a white box, keeps loading or only shows web results.

Why it works

Typing in Start is handled by a separate search process and by the Windows Search service and its index. If the service stops or the index is damaged, Start opens but search fails. Web suggestions can also hold the box up.

Steps

Open Settings → System → Troubleshoot → Other troubleshooters, find Search and Indexing and click Run. Tick the problem that matches what you see.
Press Windows + R, type services.msc, find Windows Search, right-click it and choose Restart. Set Startup type to Automatic (Delayed Start).
Rebuild the index: open Settings → Privacy & security → Searching Windows → Advanced indexing options → Advanced → Rebuild. It can take a while, and search results may be incomplete until it finishes.
End the Search (SearchHost.exe) process in Task Manager, as in Fix 1, and try again.
Optional: if search hangs while it waits for web results, switch off web suggestions with the registry command below, then restart Explorer. This is the one registry change that is widely used for this problem.

Command Prompt (Admin)

net stop wsearch
net start wsearch
reg add "HKCU\Software\Policies\Microsoft\Windows\Explorer" /v DisableSearchBoxSuggestions /t REG_DWORD /d 1 /f

net stop / net start wsearch: restarts the Windows Search service
DisableSearchBoxSuggestions: turns off web suggestions in Start search (set it to 0 or delete it to reverse)

Repair the Start components

Re-register packages, reset the layout cache and remove tools that hook the shell.

7Re-register the Start menu and shell apps with PowerShellCautionAbout 15 minutesRepairs the Start app registration

Use this when

Start does not open, shows Critical Error, or other built-in features such as Settings also misbehave.

Why it works

Start and the taskbar are built from app packages. If their registration is damaged, the shell cannot start them. Re-registering rewrites the registration from the files already on your PC. It does not delete your files or apps.

Steps

Press Ctrl + Shift + Esc to open Task Manager, choose File → Run new task, type powershell, tick Create this task with administrative privileges and click OK.
Run the first block below. It re-registers the Start menu, shell and search packages. Red errors for packages that do not exist on your PC are harmless.
Restart the PC and test Start.
Only if it still fails, run the second block, which re-registers every built-in app. It can take several minutes and may show many red lines. That is normal.
Restart again and test.

PowerShell (Administrator): Start and shell packages

foreach ($n in "Microsoft.Windows.StartMenuExperienceHost","Microsoft.Windows.ShellExperienceHost","MicrosoftWindows.Client.CBS","Microsoft.Windows.Search") {
  Get-AppxPackage -AllUsers $n | ForEach-Object { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" }
}

Get-AppxPackage -AllUsers: finds each package installed on the PC
Add-AppxPackage -Register: rewrites its registration from the files on disk

PowerShell (Administrator): all built-in apps, if needed

Get-AppXPackage -AllUsers | ForEach-Object { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" }

8Reset the Start menu layout cacheCautionAbout 10 minutesFixes a blank or glitchy Start. Pins reset.

Use this when

Start opens blank or white, pinned apps are missing, the layout is scrambled or Start crashes as soon as it opens.

Why it works

Start keeps your pinned layout in a small file in your profile. If that file is damaged, Start can crash or show nothing. Renaming it makes Windows build a new one. Your apps and files are not touched, but your pins go back to the default.

Steps

Press Ctrl + Shift + Esc and make sure you are signed in as the affected user.
Press Windows + R and paste %LocalAppData%\Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\LocalState, then press Enter.
Rename start2.bin to start2.bin.old. If you also see start.bin, rename it the same way. If the folder or file is missing, skip this fix.
Open the folder TempState next to it and delete its contents if there are any.
Restart Explorer (Fix 1) or restart the PC. Open Start. Windows rebuilds the layout.
Pin your apps again. If it did not help, rename the files back by removing .old.

Command Prompt

ren "%LocalAppData%\Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\LocalState\start2.bin" start2.bin.old

ren: renames the file so Windows creates a fresh one. Rename it back to undo

9Register the XAML packages after a 24H2 or 25H2 updateCautionAbout 10 minutesA confirmed Microsoft issue since mid-2025

Use this when

You use Windows 11 24H2 or 25H2 and Start fails to open or shows a critical error, and Settings, the taskbar or Search also fail. It often happens on a new sign-in or after provisioning a PC.

Why it works

Microsoft confirmed in November 2025 that after provisioning with a cumulative update released on or after July 2025 (for example KB5062553 or KB5065789), shell packages can fail to register in time. Explorer, Start, Settings, the taskbar and Search then misbehave. Registering the three XAML packages by hand fixes it.

Steps

Sign in as the affected user. This command registers packages for the user who runs it.
Press Ctrl + Shift + Esc to open Task Manager, choose File → Run new task, type powershell, tick Create this task with administrative privileges and click OK.
Run the three commands below, one after another.
Restart the PC and test Start, Settings and Search.
IT admins: on non-persistent setups such as VDI, Microsoft recommends a synchronous logon script that registers these packages before Explorer starts. See Microsoft's support document for the script.
Check Microsoft's Windows release health page to see whether a fix is included in your update, and install the newest update.

PowerShell (Administrator)

Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode
Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\Microsoft.UI.Xaml.CBS_8wekyb3d8bbwe\appxmanifest.xml' -DisableDevelopmentMode
Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.Core_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode

MicrosoftWindows.Client.CBS: core Windows 11 shell package
Microsoft.UI.Xaml.CBS: XAML user interface components
MicrosoftWindows.Client.Core: core client package used by the shell

💡

Do not worry about the long path

The commands point to folders that already exist on every Windows 11 PC. They do not download anything.

10Remove Start menu tweaks, then try a clean bootCautionAbout 20 to 40 minutesWhen another program is interfering

Use this when

Start broke after you installed a customization tool, a security suite or a PC maker utility, or you have used a Windows 10 style Start tool.

Why it works

Programs that change the Start menu or taskbar hook into the shell. After a Windows update they can stop matching it and crash Start. A clean boot shows whether any startup program is responsible.

Steps

Uninstall tools that change Start or the taskbar: StartAllBack, Start11, ExplorerPatcher, Windhawk mods, TranslucentTB and similar. Use Settings → Apps → Installed apps, then restart.
Temporarily turn off or uninstall third-party security suites and PC maker utilities that add overlays. Switch Windows Security back on if you remove another one.
Clean boot: press Windows + R, type msconfig, open Services, tick Hide all Microsoft services and click Disable all.
On Startup, click Open Task Manager, disable every startup app, close it, click OK and restart.
Test Start. If it works, re-enable half of the services and startup apps at a time, restarting each time, to find the one that breaks it.
When you are done, open msconfig again, choose Normal startup and restart.

Profile and policy

Find out whether your account or a policy is the cause.

11Test with a new user accountCautionAbout 15 to 30 minutesTells you if your profile is damaged

Use this when

Start fails for one user but you think the PC is otherwise fine, or the earlier fixes did not help.

Why it works

A new account has a clean profile and clean Start settings. If Start works there, your own profile is damaged and the system is fine. If it fails there too, the problem is system-wide.

Steps

Open Settings → Accounts → Other users → Add account. If Settings will not open, use the commands below in an administrator Command Prompt.
Sign out and sign in to the new account. Give Windows a few minutes to set up the profile, then test Start.
Works in the new account: copy your files from C:\Users\YourOldName (Desktop, Documents, Pictures, Downloads and so on) to the new account, then use the new account as your main one.
Fails in the new account too: the problem is system-wide. Go to Fix 5, Fix 9 and Fix 14.
Remove the test account when you no longer need it. Do not delete your old profile until you have copied everything you need.

Command Prompt (Admin)

net user TestUser * /add
net localgroup administrators TestUser /add

net user TestUser * /add: creates the account and asks you to type a password
net localgroup administrators: makes the test account an administrator so it can do the repairs

⚠️

Keep your old profile

Do not delete your old profile folder until you have copied all your files, including browser bookmarks and app data you care about.

12Check Group Policy and registry restrictionsCautionAbout 15 to 20 minutesWork, school or tweaked PCs

Use this when

The PC belongs to a workplace or school, or you changed policies or registry settings, and Start or its key shortcuts are disabled or limited.

Why it works

Policies can hide Start features, disable the Windows key or block changes to the taskbar. They override everything above, so no repair works until the policy is removed.

Steps

Run the report command below. It saves a Group Policy report to your Desktop. Open the HTML file and look under Start Menu and Taskbar.
Windows 11 Pro or Enterprise: press Windows + R, type gpedit.msc and open User Configuration → Administrative Templates → Start Menu and Taskbar. Policies set to Enabled that you did not set yourself are suspects. On your own PC, set them to Not Configured.
Windows 11 Home has no Group Policy Editor. Use the registry checks below.
Run the two registry queries. If you see values you did not set, such as NoWinKeys or DisableSearchBoxSuggestions, decide whether you need them.
Work or school PC: do not change policies. Ask your IT team, because the settings may be managed on purpose or by a company tool.

Command Prompt

gpresult /h "%USERPROFILE%\Desktop\gp-report.html"
reg query "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer"
reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\Explorer"

gpresult /h: saves a readable report of the policies applied to you
reg query: lists policy values. It changes nothing

⚠️

No random registry edits

There is no single registry fix for Start in Windows 11. Avoid copy-pasted registry tweaks from unknown pages, and back up the key before you change anything.

Recovery and last resorts

Roll back, repair Windows in place or reset it.

13Use Safe Mode, Windows Recovery and System RestoreCautionAbout 30 minutesWhen Start and Settings are both dead

Use this when

You cannot open Settings or Start, or an update broke things and you want to go back to an earlier state.

Why it works

The Windows Recovery Environment works outside the normal desktop, so a broken Start does not block it. From there you can remove the latest update or restore a working restore point.

Steps

From the sign-in screen, click the power icon, hold Shift and click Restart. Windows opens the blue recovery menu. If you are signed in, hold Shift while you click Restart in the Start menu or press Ctrl + Alt + Del and use the power icon.
Choose Troubleshoot → Advanced options.
Uninstall Updates: choose Uninstall latest quality update. If that does not help, try Uninstall latest feature update if that option is offered.
System Restore: choose System Restore and pick a restore point from before Start broke. Your documents are kept, but programs installed after that point are removed.
Safe Mode: open Startup Settings → Restart and press 4 for Safe Mode, or 5 for Safe Mode with Networking. In Safe Mode, uninstall suspect programs, run SFC and DISM (Fix 5), and test whether the problem comes from a third-party program.
From the normal desktop, you can start System Restore with Windows + R and rstrui.

14Repair install Windows 11, keeping your files and appsCautionAbout 60 to 90 minutesReplaces Windows files without removing your data

Use this when

Start and other Windows features are still broken after the fixes above, and Windows files cannot be repaired.

Why it works

A repair install reinstalls Windows over itself. It replaces every system file and resets system components, but keeps your files, apps and most settings.

Steps

Back up important files to an external drive or cloud storage first. Make sure the PC has enough free space (about 20 GB) and a stable internet connection, and plug it in.
Open Settings → System → Recovery and look for Fix problems using Windows Update, then click Reinstall now.
If Settings does not open, download the Windows 11 ISO from Microsoft, right-click it and choose Mount, then run setup.exe.
Choose to Keep personal files and apps. Use the same language and edition as your current Windows.
Let it run. The PC restarts several times. This can take an hour or more.
After it finishes, install Windows updates and test Start before you change anything else.

15Reset this PC (last resort)Removes apps or dataAbout 90 minutes or moreReinstalls Windows. Back up first.

Use this when

Every fix above failed, or the PC is too unstable to repair.

Why it works

Resetting returns Windows to a clean state. If Start still fails on a clean Windows, the cause is not your settings or apps, and you should check Microsoft's known issues or the hardware.

Steps

Back up everything to an external drive or cloud storage and save your BitLocker key and Microsoft account details.
Open Settings → System → Recovery → Reset this PC → Reset PC and choose Keep my files (removes apps and resets settings, keeps files) or Remove everything after a checked backup.
If Settings does not open, use the sign-in screen: hold Shift, click Restart, then Troubleshoot → Reset this PC.
Choose Cloud download for a fresh copy of Windows, or Local reinstall if your connection is poor.
After the reset, install Windows updates first and test Start before you reinstall your apps. Add apps back a few at a time.

🚫

Reset and reinstall are not command-line jobs

Use Settings or the recovery menu for Reset this PC and repair installs, so Windows can check for problems and show you the options (Fix 14 and 15).

Keep it from happening again

Use Restart at least once a week instead of relying on Shut down or Sleep.Keep at least 10 to 15% of drive C free.Turn on System Protection and create a restore point before large updates.Avoid Start and taskbar tweak tools, or uninstall them before big Windows updates.Keep a second administrator account for emergencies.Remember the shortcuts: Ctrl + Shift + Esc, Windows + R and Windows + I.If an update breaks Start, check Microsoft's Windows release health page before you reset anything.

Do’s and don’ts

Frequently asked questions

Why is my Windows 11 Start menu not working?

The common causes are a hung Explorer or Start process, damaged Start package registration, a bad update, a locked Windows key, a damaged profile or a policy. The 30-second diagnosis on this page points you to the right fixes.

How do I fix the Windows 11 Start button not working?

Press Ctrl + Shift + Esc, restart Windows Explorer, then end the Start and Search processes (Fix 1). If it still fails, re-register the Start packages with PowerShell (Fix 7) and check recent updates (Fix 4 and Fix 9).

Why does my Start menu not open on Windows 11 after an update?

An update can break shell packages or change a driver. Microsoft confirmed that after some cumulative updates since July 2025, Windows 11 24H2 and 25H2 can fail to register shell packages, which stops Start from opening. Register the three XAML packages (Fix 9) or remove the update (Fix 4).

What does Critical Error: Your Start menu isn't working mean?

It means the Start process could not load, usually because of damaged package registration, a profile problem or a bad update. Sign out and in, register the Start and XAML packages, repair system files and test a new user account (Fix 7, 9, 5 and 11).

How do I open Task Manager, Settings or PowerShell if Start does not work?

Use Ctrl + Shift + Esc for Task Manager, Windows + I for Settings, Windows + R for Run, and Windows + X then A for Terminal (Admin). If Windows + X fails, use Task Manager → File → Run new task. See the section on opening tools without Start.

Why does Start menu search not work in Windows 11?

The Windows Search service may be stopped, the index may be damaged, or the search process may be hung or waiting for web results. Run the Search and Indexing troubleshooter, restart the service and rebuild the index (Fix 6).

Is there a registry fix for the Windows 11 Start menu?

There is no single registry fix. One widely used setting, DisableSearchBoxSuggestions, turns off web suggestions in Start search. Avoid random registry tweaks, and use the read-only checks in Fix 12 to see whether a policy blocks Start.

Can I fix the Windows 11 Start menu from Command Prompt or PowerShell?

Yes. You can restart processes with taskkill, repair files with DISM and SFC, and re-register Start packages with Add-AppxPackage. Open an administrator window from Task Manager → Run new task if Start will not open.

Why does my Windows key not open Start but the Start button works?

A Win lock or game mode key, keyboard software, a remapped key in PowerToys or a policy such as NoWinKeys can disable the key. Test another keyboard and run the checks in Fix 3.

Why does the Start menu only fail for one user on my PC?

A damaged profile or a policy for that account is likely. Test with a new user account. If Start works there, copy your files to the new account (Fix 11), and check policies (Fix 12).

Why is my Start menu blank or white in Windows 11?

The Start layout file in your profile may be damaged, or the package registration is broken. Reset the layout cache (Fix 8), re-register the Start packages (Fix 7) and update your graphics driver.

Will resetting the Start menu layout delete my apps or files?

No. Renaming the layout file only resets your pinned layout to the default. Your apps and files are not touched. You will need to pin your apps again (Fix 8).

Is it safe to re-register all apps with PowerShell?

It is generally safe and does not delete your files or apps. It can take several minutes and show red error lines for packages that do not apply to your PC. Try the Start-specific block first (Fix 7).

Does a clean boot fix Start menu problems?

It does if a startup program or service is causing the problem. A clean boot lets you find which one. If Start still fails in a clean boot, the cause is in Windows or your profile (Fix 10 and 11).

What should I do if Start does not work on a work or school PC?

Do not change policies yourself. Group Policy or device management can control Start, and a company update can cause problems. Collect the details from the policy report in Fix 12 and contact your IT team.

My Start menu does not work on the second monitor or the taskbar is missing. What should I do?

Unplug extra monitors to test. Then open Settings → Personalization → Taskbar → Taskbar behaviors and check Show my taskbar on all displays. Restart Explorer (Fix 1) if the taskbar is missing.

Why does the Start menu not work in a virtual machine such as VMware or VirtualBox?

Low memory, no graphics acceleration and missing guest tools can make Start slow or fail. Give the VM at least 4 GB of RAM, install the guest tools and then use Fix 2 and Fix 9.

Does the same fix work for Windows 10?

Many do: restarting Explorer, SFC and DISM, re-registering apps, the Search troubleshooter and a new user account all work on Windows 10. Menus and package names differ in places, and the XAML fix is specific to Windows 11 24H2 and 25H2.

Can I get the Windows 10 style Start menu back in Windows 11?

Not with a built-in setting. Third-party tools exist, but they hook into the shell and can break Start after an update. If Start fails while you use one, remove it first (Fix 10).

Is my Windows 11 Start menu bug a hardware problem?

Almost never. Start problems come from software, updates, packages, profiles or policies. A repair install or Reset this PC that fails to fix Start is rare and should go to Microsoft or your PC maker (Fix 14 and 15).

Will Reset this PC delete my files?

Reset with Keep my files keeps your personal files but removes apps and resets settings. Remove everything deletes files, apps and settings. Always back up first (Fix 15).

How can I stop the Start menu from breaking again?

Restart weekly, keep free disk space, avoid shell tweak tools, create a restore point before big updates, keep a spare admin account and check Microsoft's release health page when an update misbehaves.

Bottom line

When the Windows 11 Start menu stops working, the cause is usually a hung Start or Explorer process, damaged shell package registration after an update, a blocked Windows key, a damaged profile or a policy. Restart Explorer and the Start processes from Task Manager, do a full restart, test the Windows key, install updates, then register the Start and XAML packages. Test a new user account before you repair or reset Windows, and back up first.
