How to Enable or Disable Windows 11 Search Indexing
Windows 11 search indexing is a background service that scans your hard drive to build a list of your files so results appear instantly. SearchIndexer.exe runs this process quietly in the background while you use your PC.
Turning off indexing stops Windows from constantly reading your drive, which saves battery life on laptops and reduces background disk activity. However, disabling this feature means searches take much longer because Windows has to look through every folder from scratch each time you type a query.
To disable Windows 11 search indexing, open Services, find “Windows Search,” click Stop, and set Startup type to Disabled. To enable it, set Startup type to Automatic (Delayed Start) and click Start .
Pros and Cons of Disabling Indexing
| Pros | Cons |
|---|---|
| Slightly lower CPU and disk usage | Search results become very slow |
| Less background disk activity | Some files may not show up in search |
| Reduced wear on older hard drives | Outlook PST files may not be searchable |
How to Rebuild the Index
Rebuilding Windows 11 search indexing fixes missing files and slow results by clearing out the old catalog and making a fresh list of everything on your computer. You can do this through the Control Panel by opening Indexing Options, clicking the Advanced button, and choosing the rebuild option to start the process over from scratch.
- Open the Control Panel and select Indexing Options.
- Click the Advanced button. Note: Changing these settings requires administrator privileges.
- Under the Troubleshooting section, click the Rebuild button.
4. Click OK. Your computer will now re-scan your files, which may take some time depending on how many files you have.
Troubleshooting Indexing Issues
If Windows 11 search indexing is paused, it often means your computer is busy or running on battery power; check that it's plugged in and the Windows Search service is configured to start automatically.
Managing Indexed Locations
Adding or removing specific folders in the Indexing Options reduces system workload by excluding unnecessary files.
Disable Windows Search Indexing
Disabling Windows 11 search indexing stops your computer from constantly running background checks on your files, which frees up system memory and CPU power. You can turn it off by opening the Services console, finding the Windows Search entry, and changing its startup type to disabled.
- Open the Services console on your PC.
- Scroll down and find the service named Windows Search.
3. Click on Windows Search to open its settings.
4. Click Stop to turn off the service immediately.
5. In the Startup type menu, select Disabled.
6. Click Apply to save.
Windows 11 search indexing is now turned off. Check the service status to confirm. It shows "Not running" when indexing is inactive. This ensures that the computer does not use resources to continuously scan files for search purposes.
Enable Windows Search Indexing
Reverting these changes requires a few specific adjustments:
- Open the Services console and find Windows Search.
- Set the Startup type to Automatic (Delayed Start).
- Click Apply.
4. Click the Start button to begin the service.
Use Command Prompt
Using Command Prompt lets you turn Windows 11 search indexing on or off quickly with a couple of short text commands. You just need to open the terminal with administrator rights and paste the specific service control command for the state you want.
Running specific commands in an elevated terminal window handles the toggle instead. Open the Command Prompt as an administrator to begin.
To enable indexing:
sc config "wsearch" start=delayed-auto && sc start "wsearch"To disable indexing:
sc stop "wsearch" && sc config "wsearch" start=disabledSummary
