How to Uninstall Windows 7 Service Pack 1 RC

While I have already mentioned in my earlier post that Windows 7 Service Pack 1 RC will add an expiry date of about one year starting from now to your installed Windows 7, there are ways to uninstall the Service Pack 1 RC safely. The exact knowledge base number of the service pack is KB976932. There are two methods of uninstalling the Service Pack that I know of, one is visually through the Control Panel and the other is through the command line. Let’s discuss both of them.

Uninstall Service Pack 1 RC through Control Panel

Uninstalling the Service Pack 1 RC through the control panel is very simple. Just go to the start menu search and write “Programs and Features” and press Enter.

This will open “Programs and Features” for managing the installed programs. On the left hand pane, select “View Installed Updates”


Now find KB976932, right click it and select Uninstall.

Uninstall Service Pack 1 RC through Command Line

If you don’t want to uninstall the Windows 7 Service Pack 1 RC through the visual process, you can use a simple command from the command prompt to uninstall the Service Pack. But the command prompt should be run as Super Administrator. To run the command prompt as Super Administrator, go to Start Search and write cmd. Now right click cmd.exe from the search results and select Run As Administrator.

Issue the following commands in the command prompt.

wusa.exe /uninstall /kb:976932

This will uninstall the Service Pack 1 RC from the PC.
