Yes, but not for this reason. We'd had computer problems with trying to uninstall games, and I'd messed up the computer with my nVidia by pressing a button in its control panel that I shouldn;t have. So we restored back to a couple of months ago using Norton Ghost backup files, then uninstalled the games, then downloaded CCleaner to clean up the messy registry. All seemed to work well, until I noticed the printer wouldn't come online. So we thought CCleaner had something to do with that and tried to restore the registry. We're hesitant to use system restore again. There's too much that could be destroyed. The printer's back and doint fine, but why can't we restore the save registry files? That doesn't make sense.
