Windows 7 (7100) Explorer.exe problems. Help!

Hi there, new to the forums but have a problem that's becoming quite a pain in the ass.

I recently upgraded from Vista Ultimate to Windows 7 RC 7100 32 bit. Everything seems to be working fine but explorer.exe just stops working every so often and crashes.

I get the error below:

Code:

Everything else open will still works but I have to close explorer.exe and reopen it before I can use the task bar again or the folder that was open.

Really been buggin me and I've been searching all day but can't find anyone with similar problems...

Any ideas as to what the problem is?

Hi eversio, welcome to the forums.

Sorry to say, but this could have been caused by the upgrade.

You might want to try this though;

From the start menu, type cmd, then right-click the result & choose 'Run as administrator' this will open it as elevated. Then type sfc /scannow to run a system file integrity check, which will highlight any system file issues.
[note this process can take a bit of time (5-10 mins)[/note]

Hope this helps :)
