Hi John,

Thanks for reaching out to Microsoft Q&A. I understand you are facing “Class not registered” and “App not associated” errors. To addition for Q&A Assist, pleas repair system files Open PowerShell or CMD as Administrator and run:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Then try re‑register all Windows apps Open PowerShell (Admin):

Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Please make sure you already Update Microsoft Store apps and reset Windows Update components.

If Settings won’t open, re-register the Settings app:

Get-AppxPackage *immersivecontrolpanel* | foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Answer 2

To resolve the "Class not registered" error you are encountering with applications like HP Smart, Facebook, and others, you may need to reinstall the affected applications. This error often indicates a corrupted file or a problem with the application's registration in Windows. Reinstalling the application can help restore the necessary files and registry entries.

Additionally, for the "APP not associated" error when trying to access Settings or System, it may be necessary to check your system's file associations or repair your Windows installation. You can also try running the System File Checker (SFC) tool to repair any corrupted system files. To do this, open an administrative command prompt and run the command:

sfc /scannow

If you continue to experience issues with frequent restart prompts, it may indicate a more serious underlying problem, such as hardware issues or critical system errors. You may want to check for Windows updates or consider performing a system restore to a point before the issues began.
