Windows 10: Windows 10 filesystem error -2144927436 when opening uwp apps and no access to start menu

Hi Microsoft Community,

I am running Windows 10.0.19041 and experiencing an issue where as far I know the following will not open on my computer:

• Start Menu
• Action/Notification Centre
• Any UWP/Store app including settings, the microsoft store and defender

When attempting to open settings and the microsoft store via the run box I encountered this error message file system error -2144927436.

So far I have attempted running sfc /scannow and dism /Online /Cleanup-Image /RestoreHealth and restarting on the completion of DISM.

I am aware of other threads with a similar issue but a different code, however the fix has always been that mentioned above DISM and sfc which hasn't worked.


Thankyou in advance!

:)

Microsoft Adds Ability to Block Win32 Apps from Install on Windows 10

Yes, UWP is an interpreter, an app running in UWP can't function without the interpreter. Only the UWP core has access to the actual hardware, the app does not.

By not having direct access to the hardware, they perform slower. UWP has to translate everything and make sure it passes safety and security checks.

If UWP has issues, all of the apps running on top of it also will. I've seen that in early release of Windows 10 where all UWP based, Windows-included apps broke (Edge, Calculator, Mail, etc.). Granted, it was only broke in one user account.
