Hi,
1. First, I suggest trying each method in this article to fix the issue:
Fix problems in Windows Search- https://learn.microsoft.com/troubleshoot/windows-client/shell-experience/fix-problems-in-windows-search
2. Run DISM and SFC tools to repair damaged system files:
On your search bar, type 'command prompt', then right-click and select 'Run as Administrator'. Type the following commands one after another in their respective order
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
Complete each step one at a time - they may take a few minutes. Restart your PC afterward.
3. If the issue continues, try a repair in-place upgrade while keeping your files and apps. This helps fix or replace any corrupted files that may be causing the problem.
Note: Before doing so, unplug all unnecessary external peripherals connected to your PC, and temporarily disable any third-party antivirus program to avoid interference.
- Click the 'Download now' button under 'Windows 11 Disk Image (ISO)' and save it to your computer: https://www.microsoft.com/software-download/windows11 (Click the third 'Download Now' button.)
- Run the downloaded file and select 'Yes' when prompted by User Account Control (UAC).
- Accept the Microsoft Software License Terms if you agree.
- On the 'What do you want to do?' screen, select 'Upgrade this PC now' and click 'Next.'
(This stage will download, verify, and create the Windows 10 or 11 installation media.) It will take some time to complete.
- Under 'Choose what to keep,' select 'Keep personal files and apps,' then click 'Next.'
- Click 'Install,' and the installation will begin. (This process will take some time, so please be patient.)
