Windows 10: How to restore windowsapp folder to its original settings?.

Hi,

A few days ago I downloaded an app Black notepad from the Microsoft store but it didn't work correctly I thought I could fix it somehow by going to where it's installed and doing something...

I searched and found that apps from Microsoft store are installed in the hidden folder C:\Program Files\WindowsApps.

I couldn't access that folder so I had to change ownership from TrustedInstaller to my account after doing that I couldn't find a way to fix Black notepad so I gave ownership back to TrustedInstaller and moved on. Today I noticed that my Nvidia Control Panel isn't working anymore and I believe it's because of what I did... now I want to restore windowsapp folder to its original settings to fix it, how can I do that?.

WindowsApps folder ownership

Hello,

As I know, the default owner for WindowsApps folder is TrustedInstaller. You can try restoring ownership to TrustedInstaller, refer first reply here for the required steps:

Restore WindowsApps permissionss to TrustedInstaller

Hope this helps!

 

Issue with folder inside WindowsApps folder

I solved this by renaming the WindowsApps folder to anything different, moving my folder back to its original location, then setting the WindowsApps folder name back again.

 

System Restore fails: AppxStaging %ProgramFiles%\WindowsApp 0x80070091

Steps taken.
Part 1/
Install W10. User -Test (No additional updates. No OEM drivers)
Create Restore Point -"Pristine"
Make a system alteration. ie; D/L and Install Google Chrome.
System Restore to RP "Pristine". (Note: Chrome should be gone.)
Successful. Chrome is gone and Edge reset. ??? Chromesetup file removed from \downloads??? Why???
New Restore Point - "Undo Restore" created by system.

Step 2/
D/L and install KB3213986. Reboot.
Make a system alteration. ie; D/L and Install Google Chrome.
Create Restore Point - "Update 1 Chrome"
Make a system alteration. Uninstall Chrome.
System Restore. (Note: Chrome should come back but may not work correctly.)
Fail. 0x80070091

To me that represents a conclusive result.

The next obvious thing to do was to roll back the Update, assuming that this will fix System Restore. However, rolling back the Update DID NOT restore the functionality of System Restore. So now my confident claim, above, is a bit shaky. If performing the update does in fact cause the issue, removing it doesn't put it right.

So now, the next obvious thing is to perform the WindowsApps rename or deletion process, to apply the fix, and run a series of testing to see if System Restore becomes stable.

Results.
Performing the WindowsApps rename fix, instead of deleting it this time, once again resulted in System Restore operating correctly. I have been able to install the remaining updates and flip back and forth between Restore Points without issue.

At this point I am done with it. My testing shows that:

• It is update KB3213986 that causes the problem to occur in the first instance.

• Rolling back the update does not correct the problem.

• Performing the known fix returns System Restore functionality.

• For how long, we don't yet know.

Should you wish to rename the WindowsApps directory rather than delete it, the attrib WindowsApps -h command line can only be performed after the icacls command line.
