Vista SP2 RC uninstall post compclean
 

Hi,
Is there a way to uninstall Vista SP2 RC after I have run compclean and
removed the "unwanted" uninstall files.

It looks like I cannot upgrade RC (why do they call it release candidate) to
the released SP2 version. I need to uninstall it.

I hope I do not have to reinstall. My Vista 64bit Ultimate install is a pain
- computer came with Vista Business 32 bit, did a 64 bit install and then
upgrade to Ultimate to get it to where it is currently.

TIA
