Vista Update May Kill MacBook Pro

I just wanted to get this out there as quickly as I could.

I own a MacBook Pro running Microsoft Vista under BootCamp and I just patched Vista with the latest updates.

The results?

My MacBook Pro will boot Vista, but after the main desktop appears it crashes out.

Clearly something in the system library files has changed, because reverting to a previous working boot fails.

This may be a terrible coincedence; but I just wanted to get the message out ASAP.

Unless you can risk loosing your machine, please be VERY, VERY careful with this.

I'd love to hear from anybody else who has been affected or people who have not. I'd like to get a full picture as to what has gone on.

Thanks
