Are you referring to the Windows Live Safety Scanner? I'm not clear what you're looking for. That's an online scanner that will check your PC for threats, but it's not meant to be used simply to free up space on your PC. If you're looking to do that, then I would recommend TFC.
Yes, I'm talking about the online scanner. Thank you, I use TFC and also CCleaner to clean temps and junk off my PC. I'm also very picky about my registry and use Regseeker. I thought my C drive was pretty clean.Before running the scanner it showed 15.7 used space; after running scanner it showed 9.3 used space. That's 6.4GB difference. The scanner checks for viruses ,open ports, temps, defrag, and registry errors. That's the way I understand what it does. I guess it's safe, it's just that I can't believe I had that much junk on my PC and thought I would post here and see what the members here had to say about it.
Thank you for your reply.
