FIX: Metro Apps Crashing on Windows 8 or 8.1

Recently something happened to my notebook with Operating SystemWindows 8.1. The problem is, when I tried to launch Music App, it keeps crashing, Check it out how I fix it!☺

Click for How to :

1. Check your Event Log -> Windows -> Application, and if you see an error like this, go to the next step!

Activation of app Microsoft.ZuneMusic_8wekyb3d8bbwe!Microsoft.ZuneMusic failed with error: This app's package family has more than one package installed. This is not supported. See the Microsoft-Windows-TWinUI/Operational log for additional information.

2. Open Registry Editor, using Run (Win+R) -> regedit -> HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Families\Microsoft.ZuneMusic_8wekyb3d8bbwe

3. Look after the key like this under Microsoft.ZuneMusic_2.2.800.0_x64__8wekyb3d8bbwe

Microsoft.ZuneMusic_2.2.800.0_x64__8wekyb3d8bbwe

4. If there's double key in number 3, delete one of them
5. And FINALLY your Music app can open normally!!!☻

Note!
2.2.800.0_x64 from Microsoft.ZuneMusic_2.2.800.0_x64__8wekyb3d8bbwe it depends on version of your Music App

Thanks for your reading, cheers!
