Windows 8 Windows 8.1 Pro No apps working including PC Settings

[Rahul Saini]

I just upgraded from Windows 7 Ultimate to Windows 8.1 Pro and got error in almost all apps which windows install. They open and just disappear. Icon remains on the taskbar but I can't maximize it again. All apps showing error even the PC settings.
I tried to open them in Safe Mode, created a new User Account but that didn't work.
WSreset.exe also didn't do anything. I tried Windows App Store Diagnosis and that also didn't do anything!
Any solutions please tell me!
Any help is appreciated!

From an elevated (right click 'runas as admin') powershell prompt

$apps = Get-ChildItem "C:\Program Files\WindowsApps"

Foreach($app in $apps)
{
Add-AppxPackages -Path "$($app.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode 2> Out-Null
}

$apps = Get-ChildItem "C:\Windows\SystemApps"

Foreach($app in $apps)
{
Add-AppxPackages -Path "$($app.FullName)\AppxManifest.xml" -Register -DisableDevelopmentMode 2> Out-Null
}

Thanks for the help but I just came to know that my Windows is missing C:/Windows/SystemApps folder. Is there any way I can get this thing right without reinstalling the winodws.

That's from Windows 10. It may not exist or might be called something different on Windows 8.

Is it C:/Program Files/Windows Apps?

No space between windows and apps. You can also just go look in that directory. It's probably a hidden directory
