Unable to uninstall Vista beta service pack

I think I may have a problem: I have installed the Vista beta service pack (6001). But I don't know how to uninstall it. I have gone to add/remove programs/view installed updates and it doesn't appear there. I definitely have it, because under My Computer it says:

Windows Vista ™ Ultimate
Service Pack 1, v668

On my desktop, on the bottom right hand corner, it says: Windows Vista ™ evaluation copy. Build 6001.

In Windows Updates, it has an entry on 15/12/2007: Update for Windows Vista (KB937287) - Build 6001.17052 (x86). Status: successful. When I double click on it, the information panel says (among other things) it cannot be uninstalled.

It has another entry, also 15/12/2007: Vista Service Pack 1 Release Candidate 1 - Bulid 6001.17052 (x86). Status: failed.


I believe that I have to uninstall the beta service pack before I can load the full version when it is released. Also, I believe the beta version expires in either June or July.

So where do I go from here? How do I uninstall it?

Thank you for your reply. None of the above work, so reinstall it must be. Ugh...Vista

Your welcome David. Sorry the reinstall was the option you had to use.

I had to do a fresh install before installing SP1 RTM but I'm glad I did.
My system is very stable and responsive now. No major issues at all.
The beta improved things quie a bit but since performing a fresh install and
SP1, my system runs great.
