If you’re seeing an error in the event log that looks like this:

Activation context generation failed for "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger\ia64\msvsmon.exe". Dependent Assembly Microsoft.Windows.Common-Controls,language="*",processorArchitecture="ia64",publicKeyToken="6595b64144ccf1df",type="win32",version="" could not be found. Please use sxstrace.exe for detailed diagnosis

And it’s occurring at about 00:30 every day, it seems to be caused by the scheduled task ProgramDataUpdater. It looks like it’s choking on the ia64 binary, and if you don’t need the Itanium version you could resolve it by renaming or deleting the exe, similar to this KB article:
