Apps / Software :: Windows 8.1 / Most Metro Apps Crash Immediately At Launch

having installed and configured all the software I need, I felt almost ready and relieved to finally create a backup image of my system. However, I have just realised that most built-in Metro Apps have stopped working.

In detail, Weather, Maps, Mail, Skype, Calendar, Contact, Stocks (and probably few more) do not work, i.e., when I click-open them, there is the short animation in which the App symbol is magnified to full screen, and then immediately afterwards I am sent back to the Metro interface. However, the apps do still appear in the Metro Apps' taskbar on the left side of the screen. Re-Opening them from there leads gives the same result.

Very few apps work, like Skydrive, Photos and Store.

I can confirm that I neither had this issue with Windows 8 nor right after my Windows 8.1 installation, which is when I checked Metro apps for the last time.

What settings in the meantime have caused this disruption, I can only say that I have not done any real work with the computer since the fresh install but merely installed and configured everything to my specifications.

Just for the sake of ruling out some possible causes, I can confirm that: I have no third-party firewall or antivirus programs installed; that I have no nvidia or ATI/AMD graphics card, just the Intel HD 4000 onboard graphics; and that I use the most recent drivers everywhere.

I have already read Windows Store Apps Troubleshooter - Fix Apps in Windows 8 and gone through most of the points, except the refresh install, which I would like to avoid since this is a newly installed computer.

The following errors are reported in the application event log of Windows:

1) Event id 10: "Fehler beim Laden der Anwendungseinstellungen for Paket "Microsoft.BingMaps_8wekyb3d8bbwe". Fehlercode: 5" This is the original German message, translated to english this means:

"Error loading applications settings for package "...". Error code: 5"

I get this type of error for every app I launch, and a few more errors like:

2) Event id 5973: "Translated: The following error occurred while activating the app "...": The remote procedure call failed. You can find more information in the protocoll/log "Microsoft-Windows-TWinUI/Idle""

3) Event id 1000: "Name der fehlerhaften Anwendung: Map.exe, Version: 2.0.2210.2336, Zeitstempel: 0x5257124f
