My alternate drive has been failing for a while, and after several hangups trying to start the computer, I decided I had enough and disconnected the hard drive from the computer. Going through add or remove programs, I have found several programs still listed from that drive, and can't uninstall because the drive doesn't exist anymore.
I have tried running CCleaner to remove the registry listings, and I have run sfc /scannow. not sure what else to do.
