How to fix and reset Windows Search on Windows 11
Windows 11 search stopped finding apps or files? Fix it in order: run the troubleshooter, restart the Windows Search service, rebuild the index, then reset it.
When Windows 11 search stops finding your apps or files, or the search box goes blank and won’t take any typing, the fix is almost always a software reset rather than a reinstall. Work through it in order: restart, run the troubleshooter, restart the Windows Search service, then rebuild the index. Only if all of that fails do you reset Search itself. Every step here is built into Windows, and none of them touch your personal files.
Restart, then run the troubleshooter
Start with a restart. It ends the background SearchHost.exe process that draws the search box, installs any pending updates, and clears the most common temporary glitch on its own. If the box won’t open or won’t accept text, a restart is the fastest thing to try.
If search is still broken, run the built-in troubleshooter. In Windows 11, go to Settings > System > Troubleshoot > Other troubleshooters and run Search and Indexing if it appears in the list. Windows also runs this troubleshooter automatically when it detects a problem, and it resets Search to its default behavior. Microsoft has been retiring some of the older troubleshooters, so if you don’t see it listed, move on — the manual steps below do the same work.
If your real complaint is that one specific program or file never comes up, it may not be a Search fault at all; check how to fix “Windows cannot find” errors before you rebuild anything.
Restart the Windows Search service
Search is driven by a background service named Windows Search (wsearch). Restarting it clears a stuck indexer without a full reboot. Open the Services console by typing services.msc into the taskbar search — or, if the box itself is dead, press Ctrl+Shift+Esc, open Task Manager, and use its Services tab. Find Windows Search, right-click it, and choose Restart.
While you’re there, confirm the service is set up the way Microsoft specifies: its status should be Running and its startup type Automatic (Delayed Start). Some antivirus tools and “PC optimizer” apps disable this service, which quietly breaks search; if yours is disabled, that is likely the whole problem. You can also force a clean restart of just the search box by ending the SearchHost.exe process in Task Manager’s Details tab — Windows starts it again the next time you search.
Check the indexing status
Search only finds what it has indexed, so the next thing to read is the indexer’s own status. Go to Settings > Privacy & security > Searching Windows and look at the Indexed count and the status message. When everything is healthy it reads Indexing complete. Anything else tells you what to do, and often the answer is simply to wait or to plug the laptop in.
| Status message | What it means | What to do |
|---|---|---|
| Indexing complete | The indexer has finished | If files are still missing, confirm the right folders are set to be indexed under Advanced indexing options |
| Indexing in progress | New files are still being added | Leave the PC on and plugged in for a few hours to let it finish |
| Indexing is paused to conserve battery power | Low battery stopped it | Connect the charger; indexing resumes once the battery recovers |
| Indexing is paused | Paused from this settings page | It resumes in 15 minutes, or restart the wsearch service to resume now |
| Insufficient disk space to continue indexing | The drive is nearly full | Keep more than 1 GB free, then let indexing catch up |
A nearly full drive stops the indexer and drags the whole machine down, so if that’s your message, free up space on Windows 11 before you go any further.
Rebuild the search index
If the status looks fine but results are still wrong or missing, rebuild the index from scratch. Go to Settings > Privacy & security > Searching Windows > Advanced indexing options, select Advanced, and choose Rebuild. This deletes the index database and builds a new one, which is the standard fix for stale or corrupted results.
Give it time. Microsoft says to let the indexer run for up to 24 hours to finish a rebuild, though most personal PCs take far less. Keep the machine on and plugged in while it works, and expect search to be incomplete until it’s done. A rebuild is also worth doing after you change which folders are indexed. Because indexing leans hard on the disk, a rebuild can briefly make an already sluggish PC feel worse; if yours was slow to start with, these steps for a slow Windows PC are worth a read.
Reset Search as a last resort
If nothing above works, reset Search itself. On Windows 11, Microsoft provides a PowerShell script named ResetWindowsSearchBox.ps1 for exactly this, and you need administrator rights to run it. Download it from Microsoft’s Reset Windows Search PowerShell script page, then right-click the saved file and choose Run with PowerShell.
If it refuses to run, your system’s script policy is blocking it. Open an elevated PowerShell window, check the current setting with Get-ExecutionPolicy, and if needed allow scripts for your account with Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted. Run the reset, then set the policy back to what it was before. Resetting Search does not delete your files, though results may feel less relevant for a short while as the index rebuilds behind the scenes.
Worked in this order — restart, troubleshooter, service, index status, rebuild, reset — most Windows 11 search problems clear up well before the final step, and none of them cost you any data. If search still fails after a full reset, the trouble is likely deeper in your user profile or the drive itself, and signing in to a fresh Windows account is the usual next test to tell those two apart.
