How to uninstall Windows 7.0 SP1 Beta

today  I was about to update my machine with a newer version of Service pack of windows 7.0. I downloaded RC1 and when I clicked on install it said unable to continue a pervious version is installed. so tried a simple way of uninstalling the SP beta but as usual there wasn’t any so this a simple way to do it.

If you've used the Disk Cleanup Wizard since you've installed SP1 RC, the backup files needed to uninstall the service pack might have been removed from your computer. If that's the case, then use System Restore to uninstall the service pack.

  1. Click the Start button .

  2. In the search box, type command prompt.

  3. In the list of results, right-click Command Prompt, and then click Run as administrator.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

  4. Type the following: wusa.exe /uninstall /kb:976932

  5. Press Enter.
