How To Uninstall Windows 7 Service Pack 1 (SP1) Beta or Windows Server 2008 R2 SP1 Beta?
Microsoft few days back officially released Windows 7 SP1 Beta for public download. The beta version will expire on June 30, 2011 and after the expiration, users will have to either upgrade to a newer build or uninstall and return to the RTM build.
Users will not be able to upgrade directly from SP1 Beta to the final version of Windows 7 SP1. So, if a user installs SP1 Beta, then they will have to first uninstall it before installing SP1 final. If Windows 7 SP1 Beta uninstall routine fails, then the user has to do a clean install of Windows 7, which no user will like. Anyways, Microsoft has provided a simple guide on how to uninstall and remove Windows 7 SP1 Beta and revert back to the RTM build.
Windows 7 SP1 Beta do creates backup files that are needed for uninstalling SP1 Beta later. But, if a user uses Disk Cleanup Wizard, the backup files needed to uninstall SP1 Beta might get deleted. Then the only option to remove SP1 Beta will be through the System Restore utility.
This uninstall process of SP1 applies both to Windows 7 SP1 Beta and Windows Server 2008 R2 SP1 Beta.
