Hello,
Thank you for posting in Microsoft Community forum.
Based on the description, I understand your question is related to "Change your password" opens and closes the window with no feedback.
- First try run below command in powershell: Get-AppXPackage | foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
- Then try use these commands to scan system files in cmd: sfc /scannow DISM.exe /Online /Cleanup-image /Restorehealth
- Right-click on the Settings app and select “App settings”. Scroll down and click on “Reset”.
- Try creating a new user account and see if the problem persists. Go to Settings > Accounts > Family & other users > Add someone else to this PC.
Have a nice day.
Best Regards,
Molly
