Windows 7 Home Premium, service pack 1. I recently turned on the built in Backup and Restore facility, pointing it at an external USB drive (500GB) I'd bought for the purpose. Now, I can't unmount the USB drive, the computer is much slower, noisier, and swaps out more. I can't delete the files from the USB drive, and the Backup control panel says there is no backup there, but the files are there and consuming half the drive.
And, I can't turn off the Backup service!
Is it possible to turn off Windows 7 built in backup service once you've given it a drive? I know how to stop a particular backup run, I want to completely permanently turn off the Backup and Restore service.
