Reinstall and Re-register Apps in Windows 10

Somebody, please help. I tried to do step 2 on the first option to fix windows apps problem, but after that the start menu and cortana won't work. I can't even open the windows settings anymore. When I tried to open sticky notes which is pinned on my taskbar it said explorer.exe Class not registered. And when I tried to boot into safe mode I got explorer.exe Unknown hard error. I tried to do in place upgrade to fix it but still not working. Is there a way to fix it without reinstalling windows?

Hello,

Usually if a repair install can't fix it, it's time for a clean install of Windows.

I agree with @Brink . . .

If you go down this route, I would also advise [ Recommend ] that you Export [ Backup ] your Drivers . . .

I hope this helps.

The Windows Store app would open and crash after a few seconds. Option one Step 3 was the only thing that worked after trying many other fixes.
Great work on this post Shawn!

I put it in

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *MSPaint*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

but it keeps saying:


= : The term '=' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct
and try again.

Hello Keith, and welcome to Ten Forums.

It looks like you are running the command in PowerShell instead of Command Prompt.
