Windows Media Store Crashes and disableUpdateDiscSvc
If you use a third party guide provider for Vista Media Center then you probably use the disableUpdateDiscSvc registry key. There is a bug in Vista that causes the Windows Media Store Update Manager to crash if the key/setting is enabled.
This bug is known by Microsoft (KB935685) but the fix is only available for download by calling Microsoft.
Luckily someone has uploaded the hotfix to www.xpmediacenter.com.au.
