Vista Service Pack 1 Release Candidate

I cannot recommend that anyone install the just released SP1RC for Vista.

Using a non-production computer running Vista Ultimate, I followed Microsoft’s instructions to the letter, adding the extra step of creating a restore point before beginning the installation process. The process first installs 3 Windows updates over a period of a couple of days, then it begins the Service Pack upgrade. The upgrades installed without a problem, but the installation of the Service Pack hung up at 0% completed. It stayed in that state for over 10 hours. There was no indication of an error, just no progress. Windows couldn’t load beyond the welcome screen. During this time I was unable to access my desktop or applications.

I’m not even linking to the SP1 update sites. If you really want to try it, you can find it. But I recommend you don’t bother.
