Windows 11 Start Menu Search Not Working? 9 Ways to Fix It

If Windows 11 Start menu search stops working, first end SearchHost.exe in Task Manager’s Details tab (Fix #1); Microsoft says Windows Search starts again automatically the next time you search. The problem usually looks like one of three things: you press the Windows key and start typing but nothing appears, the search panel opens completely blank, or it returns no results for apps and files you know are on the PC. If the Start button itself does nothing, or you see a “Critical Error” message, the whole Start menu is broken rather than just search, so jump to our Windows 11 Start Menu Critical Error: How to Fix It guide instead.

Quick Diagnosis: Match Your Symptom to a Fix

• Search panel is blank or won’t accept typing: Start with Fix #1 (restart SearchHost.exe). It’s quick and doesn’t need a reboot.
• Taskbar and Start feel frozen along with search: Go to Fix #2 (restart Windows Explorer).
• Search opens fine but finds nothing, or misses files you know exist: Work through Fix #3 (Windows Search service), Fix #4 (indexing settings), and Fix #5 (rebuild the index).
• Search text looks garbled or won’t render properly: Try Fix #7 (Windows Font Cache Service).
• Search broke right after a Windows update: Check Fix #8 (install the latest update).
• Search works in a different user account but not yours: Skip ahead to Fix #9 (profile-specific repair).

The fixes run from quickest to most involved. Several later steps need an administrator account, so sign in as an admin before you start.

Fixes for Windows 11 Start Menu Search

Fix #1: Restart SearchHost.exe in Task Manager

Symptoms: The search panel opens blank, or you can’t type into it.

Why it happens: SearchHost.exe is the Windows 11 Search process. If it hangs, the search panel can stop responding even when the index itself is fine. Microsoft notes that ending it stops Windows Search, and that Windows Search starts automatically the next time you search.

• Press Ctrl + Shift + Esc to open Task Manager.
• Select the Details tab in the left sidebar.
• Scroll down to SearchHost.exe, or type it into the search box at the top of Task Manager.
• Right-click SearchHost.exe and select End task.

• Click End process to confirm.
• Press the Windows key or click the search box on the taskbar to reopen search.

Verify it worked: Type the name of an app you use often, like “Notepad.” If it appears as you type, you’re done.

Fix #2: Restart Windows Explorer

Symptoms: The taskbar, Start menu, and search all feel frozen or slow to respond together.

Why it happens: Windows Explorer hosts the taskbar and Start shell. If Explorer itself is stuck, search can’t respond no matter how healthy the search index is. Restarting Explorer is a widely used troubleshooting step for a frozen shell; it often helps with frozen taskbar, Start, and search symptoms together, though results can vary depending on what’s actually causing the freeze.

• Press Ctrl + Shift + Esc to open Task Manager.
• Select the Processes tab.
• Find Windows Explorer in the list.
• Right-click Windows Explorer and select Restart.

• Wait a few seconds. The taskbar briefly disappears and then comes back.

Verify it worked: Open search and type a query. The panel should respond normally and show results.

Fix #3: Restart the Windows Search Service

Symptoms: Search opens and accepts typing, but returns no results or only some of what you expect.

Why it happens: The Windows Search service (its short name is wsearch) builds and maintains the index that makes results appear instantly. If it has stopped, or indexing has paused, results go missing. Microsoft notes that indexing can pause during certain system activity, including Windows upgrades. Restarting the service resumes it right away. Otherwise it resumes on its own after roughly 15 minutes.

• Press Win + R, type services.msc, and press Enter.
• Scroll down to Windows Search.
• Right-click Windows Search and select Restart. If the service isn’t running, select Start instead.
• Right-click Windows Search again and select Properties.
• Check the Startup type (on most Windows 11 installations this defaults to Automatic (Delayed Start)) and confirm Service status shows Running.

• If Startup type is set to Disabled or Manual and the service isn’t running when you need it, change it to Automatic (Delayed Start) (the typical default) and click Apply, then OK.

Verify it worked: Search for a file you saved recently. If it’s still missing, the index may need time to catch up or a full rebuild (Fix #5).

Fix #4: Check Your Searching Windows Settings

Symptoms: Search finds apps but not your documents, or finds files in some folders but not others.

Why it happens: Windows 11 only searches the locations you’ve told it to index. The default Classic mode typically covers standard locations such as your Documents, Pictures, and Desktop folders, though the exact set of indexed folders can vary by setup; Advanced indexing options > Modify shows the exact list on your PC. Files stored elsewhere won’t show up.

• Open Settings > Privacy & security > Searching Windows.
• Look at the indexing status near the top of the page. It shows how many items are indexed and whether indexing is running or paused.
• Under Find my files, pick a mode:
  • Classic typically indexes your standard user folders (such as Documents, Pictures, and Desktop). This is the default.
  • Enhanced indexes the entire PC. It finds more, but the first index build takes longer and uses more resources while it runs.

• If you stay on Classic, scroll down and add any folders you need searched using the customize search locations option on the same page.

Microsoft occasionally renames labels on this page, so the wording may differ slightly on your build.

Verify it worked: Leave the PC on for a while so the indexed item count can grow, then search for a file from the newly added location.

Tip: If you switch to Enhanced on an older laptop with a spinning hard drive, expect the first build to be slow. Index builds finish much faster after an SSD upgrade.

Fix #5: Rebuild the Search Index

Symptoms: Search returns wrong, stale, or missing results even after restarting the service and checking your settings.

Why it happens: The index database itself can become damaged. A rebuild deletes it and creates a fresh one from scratch.

• Open Settings > Privacy & security > Searching Windows.
• Scroll down and click Advanced indexing options. The classic Indexing Options window opens.
• Click Advanced. Approve the administrator prompt if one appears.
• Make sure the Index Settings tab is selected.
• Under Troubleshooting, click Rebuild.

• Click OK in the warning that says the rebuild might take a long time.

How long it takes: Microsoft notes that rebuilding the index takes time, and the exact duration depends on how many files you have — it can range from several minutes on a lightly used PC to many hours on one with a large number of files. Search results will be incomplete until it finishes. Keep the PC on and plugged in so it can keep working.

Verify it worked: Recheck the indexed item count in Searching Windows. When it stops climbing and indexing reports complete, test search again.

Fix #6: Run the Search and Indexing Troubleshooter

Symptoms: You’ve tried the fixes above and search still misbehaves, or you’d rather let Windows find the problem for you.

Why it happens: The troubleshooter checks common Search and indexing problems, such as permissions and service state, and repairs what it can automatically.

Microsoft documents launching it with a command:

• Click Start, type cmd, then select Run as administrator. If search itself is broken, press Win + R, type cmd, and press Ctrl + Shift + Enter instead.
• Run this command:

msdt.exe -ep WindowsHelp id SearchDiagnostic

• Follow the prompts. Tick the checkboxes that describe your problem, such as files not appearing in results.
• Apply any fixes it recommends, then restart the PC.

Microsoft has been retiring legacy MSDT-based troubleshooters. If this command doesn’t open anything on your build, skip to Fix #7. Don’t use the old Windows 10 path through Update & Security, because it doesn’t exist in Windows 11.

Verify it worked: After the restart, open search and run a few test queries.

Fix #7: Restart the Windows Font Cache Service

Symptoms: The search panel opens, but text is garbled, missing, or not drawn properly.

Why it happens: It sounds unrelated, but Microsoft specifically documents restarting this service to fix certain search display failures.

• Press Win + R, type services.msc, and press Enter.
• Find Windows Font Cache Service.
• Right-click it and select Stop.
• Open search and test it.
• Go back to Services, right-click Windows Font Cache Service, and select Start.

Verify it worked: Search should display text normally. If text still looks wrong after you start the service again, restart the PC.

Fix #8: Install the Latest Windows Update

Symptoms: Search has been flaky since a recent update.

Why it happens: Shell and Explorer regressions can occasionally arrive in one cumulative update and may be addressed in a later one. Microsoft tracks active problems separately for each release on its Windows release health known-issues pages — check whichever page matches the version shown in Settings > System > About: Windows 11, version 26H2 or Windows 11, version 25H2.

• Open Settings > Windows Update.
• Click Check for updates.
• Install the available security and quality updates. Install an optional (preview) update only if its release notes mention a fix for your search problem, because preview updates are pre-release quality.
• Restart when prompted.

To confirm you’re on a supported release, check Settings > System > About. Microsoft lists supported Windows 11 versions on its supported versions page.

If you suspect corrupted system files rather than a buggy update, run SFC and DISM. Our How to Use SFC and DISM to Repair Windows System Files guide covers both.

Verify it worked: After the restart, give the index a few minutes to resume, then test search.

Fix #9: Repair Search for Your User Profile (Advanced)

Symptoms: Search works in a brand-new or other Windows account, but not in yours.

Why it happens: The Search app stores per-user data in a package folder and a registry key. If either is damaged, often only that profile is affected, although other per-user settings, permissions, or policies can cause the same symptom. The steps below follow the Windows 11 profile repair in Microsoft’s Fix problems in Windows Search article (“Regenerate the package AppData folder”). Before you start, confirm that search works in a newly created account; if it doesn’t, this fix isn’t the right one.

Back up first: This fix deletes a per-user data folder and a registry key. Before you touch anything, back up important files to an external hard drive and, if possible, create a system restore point. This is a deliberate, somewhat invasive repair — don’t start Part 1 until your backup is done.

Part 1: Delete the Search package folder

• Sign out of the affected account and sign in to a different administrator account.
• Open File Explorer and go to the affected user’s folder: C:\Users\AffectedUserName\AppData\Local\Packages\. Replace AffectedUserName with the real folder name. AppData is hidden, so turn on hidden items under View > Show > Hidden items if needed.
• Find the folder Microsoft names for Windows 11, MicrosoftWindows.Client.CBS_cw5n1h2txyewy, and delete it. If that exact folder isn’t there, stop and don’t guess at a different folder.
• Sign out of the admin account.

Part 2: Reset the registry key and re-register Search

• Sign back in to the affected account. Run the remaining steps while signed in as this account — the package registration applies per-user, so doing this from a different account’s session won’t fix the affected profile unless Microsoft’s current documentation for your version says otherwise.
• Press Win + R, type regedit, and press Enter.
• Go to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search.
• Right-click the Search key and select Export to save a backup.
• Right-click the Search key again and select Delete.
• Right-click Start, select Terminal (Admin), and confirm the Windows 11 manifest Microsoft references is present:

Test-Path "C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\Appxmanifest.xml"

If this returns False, stop: restore the key you exported (double-click the .reg file) and ask for help instead of guessing at a different folder.

• If Test-Path returned True, run the Windows 11 command from Microsoft’s article:

Add-AppxPackage -Path "C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -Register

This re-registers the package from its manifest. Microsoft says the restart in the next step restarts indexing and regenerates the registry key and the AppData folder.

• Restart the PC.

Verify it worked: Sign in to the affected account and test search. If it still fails, double-click the .reg file you exported to restore the original key.

Microsoft’s article also mentions a Windows Search reset script. Use the version linked from that article, not a copy from a third-party site, and avoid “search fixer” utilities.

Settings to Check

• Find my files mode: Settings > Privacy & security > Searching Windows. Classic covers standard folders, while Enhanced covers the whole PC.
• Windows Search startup type: services.msc > Windows Search > Properties. This typically defaults to Automatic (Delayed Start), and Service status should show Running.
• Indexed locations: Advanced indexing options > Modify. Make sure the folders you search are actually included.
• Index rebuild: Indexing Options > Advanced > Index Settings > Rebuild. Only use this when results are wrong, because a rebuild can take a long time to finish, depending on how many files you have.

Getting Help

If none of the nine fixes work, collect a few details before you ask for help. Note your Windows version from Settings > System > About, the exact symptom, and which fixes you’ve tried. Then post them in Microsoft Q&A, where other users have reported similar Windows 11 search problems.

Microsoft’s two official references go deeper than this article:

• Fix problems in Windows Search
• Troubleshoot Windows Search performance

If search works from the Start menu but File Explorer’s search box doesn’t, see our File Explorer Search Not Working in Windows 11 guide. While you troubleshoot, File Explorer’s search box is also a handy workaround for finding files in a specific folder.

Prevention Tips

• Let updates finish: Indexing pauses during upgrades. Leave the PC on after a big update so indexing can catch up.
• Don’t disable Windows Search: Some “debloat” guides suggest turning off the service. That breaks Start menu file search entirely.
• Keep your drive healthy: A nearly full drive slows indexing. Free up space, or move bulky files to an external drive.
• Protect against sudden shutdowns: An abrupt power loss while Windows is indexing is one possible cause of index problems. A UPS on a desktop PC reduces the chance of that happening.

Help & Answers

Frequently Asked Questions

8 questions

What’s the difference between search not working and the Start menu being broken?

If Start opens but search is blank, frozen, or returns nothing, it’s a search problem and this article applies. If the Start button does nothing or you get a “Critical Error” message, the whole Start shell has failed. Use our Critical Error guide for that.

What’s the fastest fix when search opens blank or won’t let me type?

End SearchHost.exe in Task Manager’s Details tab (Fix #1). Microsoft says Windows Search starts automatically the next time you search, so you don’t need to reboot.

How do I restart the Windows Search service?

Open services.msc, right-click Windows Search, and select Restart, or Start if it isn’t running. Then confirm its startup type, which typically defaults to Automatic (Delayed Start).

Where are the search indexing settings in Windows 11?

They’re under Settings > Privacy & security > Searching Windows. The older Indexing Options dialog opens from the Advanced indexing options link on that page.

How long does rebuilding the index take?

Microsoft notes that rebuilding takes time, and the exact duration depends on how many files are on your PC — it can range from minutes to many hours. Results stay incomplete until it finishes.

Is there an official troubleshooter for search problems?

Yes. Microsoft documents msdt.exe -ep WindowsHelp id SearchDiagnostic, run from an elevated Command Prompt. Because Microsoft is retiring legacy troubleshooters, the command may not launch on every build.

Why does search work on one account but not another?

Each account keeps its own Search package data and registry key. If those are damaged, often only that account is affected, though other per-user settings or policies can cause the same symptom. Fix #9 resets them.

Could a Windows update be causing this?

It’s possible. Update-related shell regressions can happen, and they’re sometimes addressed in a later cumulative update. Install the available updates in Settings > Windows Update, and check Microsoft’s release health page for your version for known issues.

Wrapping Up

Ending SearchHost.exe (Fix #1) is the fix to try first, because it’s quick and Microsoft documents it for unresponsive search. If results are missing rather than the panel being dead, restart the Windows Search service and then, if needed, rebuild the index, giving the rebuild time to finish. If search keeps breaking again within days, look deeper. Run SFC and DISM, scan for malware, and check your drive’s health, because a failing disk can keep corrupting the index.

Step	Action	Applies to
Fix #1	End SearchHost.exe	Blank panel, can’t type
Fix #2	Restart Windows Explorer	Frozen taskbar and Start
Fix #3	Restart Windows Search service	No or partial results
Fix #4	Check Searching Windows settings	Files missing from some folders
Fix #5	Rebuild the index	Wrong or stale results
Fix #6	Run the Search troubleshooter	Persistent indexing problems
Fix #7	Restart Windows Font Cache Service	Garbled search text
