I just click the OK button and it goes away and continues with shutdown.

I did a clean install, Groze and I know I didn't see it until about three or four days ago. So, yeah, I think I did! :)

Whatcha thinkin'? An update did it? If so, I think I agree with you.

I don't think anything you did caused the error, because I have the same one on all my HP computers. Every time I shut down, I get the error. And, each time I get the error, the middle 8 digits...
