Since you're dual-booting, I'll assume this was a "clean" install, correct?
Did this occur immediately after install or did you make any major changes to your system or install any software that may have caused this problem to occur?
Did you receive driver updates fro Windows Update?
You might want to take a look under Optional Updates and see if anything other than the language packs is available.
I've had Explorer do the same thing on a couple occasions, but it never crashed all my open programs, just Windows Explorer.
