While installing SP1 for Windows Vista tonight, I was presented with the dialog box invited me to click on "Things you should know before installing Service Pack 1", which I decided to click.   This leads to KB Article 936330, which are the Release Notes for the Release Candidate.   It’s pretty standard stuff, but one thing was quite peculiar:

 

After you uninstall Service Pack for Windows (KB936330), we recommend that you wait at least one hour before you try to install the final release of Windows Vista SP1.

 

Is this to prevent cramping?   Is this an inside joke?

 

Maybe it has a real world reason, such as DLL caches clearing after uninstall?   Does anyone have a reason?

    It is to do with rolling back of files and registry entries. in one of the rc's the readme gave a reg command to run which if it returned any output meant you had to wait a little longer before jumping in with the new beta service pack.
