You're off topic for this forum, which is dedicated to
Windows Live OneCare.
The Safety Scanner forums were here:
http://boards.live.com/safetyboards/board.aspx?BoardID=225
That scanner no longer exists and the new scanner does not perform a "tune-up". You can use the Windows tools such as Disk Cleanup and Defrag. I don't recommend the use of a registry scanner, which was part of the Safety Scanner. See:
