I have Windows 8. (Not 8.1)
Metro apps won't open, i.e. Mail, Photos, Weather, Games, Sport, Bing, Travel, Skype...
Windows Store works until installing an app, to which I get the error message "Something happened and the windows store is no longer working, please restart/refresh windows on your PC"
I have tried typing "SFC /scannow" in the command line but I get the error that it contains corrupt files it cannot fix.
I have tried the ordinary Windows metro apps troubleshooter and it explains that either the display adapters are out of date (I have updated them) or Windows Store Configuration may be damaged. That may narrow down the problem.
I have tried running the command - "powershell -ExecutionPolicy Unrestricted Add-AppxPackageDisableDevelopmentMode Register$Env:SystemRoot\WinStore\AppxManifest.XML" but get the following error message - "Deployment failed, the package repository is corrupted".
Also, it seems that registries have full permissions to ALL APP PACKAGES so that's not an issue either.
Hopefully there is enough information above to identify the problem. Thanks for any help in advance.
