I was reading a Windows article about how to uninstall SP1 ( no, I have no intention to uninstall ).
I came across this pharagraph ......
If you've used Disk Cleanup since installing SP1, the backup files needed to uninstall the service pack might have been deleted from your computer. To remove the service pack, you'll need to reinstall Windows 7. For installation information, see Installing and reinstalling Windows 7
Which backup file is that ?
Where do I find it in disk cleanup list.
I want to uncheck it so I still have the option to uninstall if I want to.
