How to rebuild Search Index in Windows 11/10

If you find that search results are missing, no longer valid, or incorrect, then the Search Index may not be up to date – in which case, you can manually rebuild the index to force it to update. In this post, we will show you the two ways to rebuild the Search Index if it’s not working as it should, on your Windows 11/10 device.

How to rebuild Search Index

Windows Search has been significantly improved to limit the number of times the service indexes your files for content that doesn’t have an impact on search experiences and gives you a better experience on Windows 11/10.

You can rebuild the search index in Windows in two quick and easy ways.

1] Rebuild Search Index via Control Panel

To Rebuild Search Index via Control Panel in Windows, do the following:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type control and hit Enter to open Control Panel.
• From the top right corner of the window, set the View by option to Large icons or Small icons.
• Click Indexing Options.
• In the window that opens, click the Advanced button.
• In the Index Settings tab, click the Rebuild button under Troubleshooting.
• Click OK on the prompt to confirm.
• The indexing operation will now commence.
• Click the Close button when the indexing completes & exit Control Panel

Keep in mind that rebuilding the index might take a long time to complete. At any time, you can click the Pause button to stop rebuilding the index.

2] Rebuild Search Index using Batch (.BAT) file

To Rebuild Search Index using a batch (.bat) file in Windows, do the following:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type notepad and hit Enter to open Notepad.
• Copy and paste either of the code below into the text editor.

@echo off
net stop wsearch
del "%ProgramData%\Microsoft\Search\Data\Applications\Windows\Windows.edb"
:wsearch
net start wsearch
IF NOT %ERRORLEVEL%==0 (goto :wsearch) ELSE goto :END
:END

OR

@echo off
net stop wsearch
REG ADD "HKLM\SOFTWARE\Microsoft\Windows Search" /v SetupCompletedSuccessfully /t REG_DWORD /d 0 /f
del "%ProgramData%\Microsoft\Search\Data\Applications\Windows\Windows.edb"
:wsearch
net start wsearch
IF NOT %ERRORLEVEL%==0 (goto :wsearch) ELSE goto :END
:END

• Save the file to the desktop with a name and append the .bat file extension – eg, SIRebuild.bat and on the Save as type box select All Files.
• To run the batch file right-click the saved file and select Run as Administrator from the context menu.
• Click Yes on the UAC prompt to approve. The search index will now start to rebuild in the background.

That’s it.
