You have joined a Windows 8 computer to Active Directory domain and then you went to try to update the store apps and it failed? The issue is because you had installed the apps before joining the domain, so the apps were under one account, while the domain join has another windows store account.
Microsoft has released in last few days new KB2785094 that address among others issues also this one.
This cumulative update includes the following performance and reliability improvements:
- Resolves an issue that could cause low-quality playback when you stream videos from Windows Media Center to Xbox consoles.
- Improves Bluetooth audio playback quality.
- Resolves an issue in which you may be unable to install a Windows Store app update when the app is installed to multiple accounts on the same computer.
