I own this OS and for some reason many programs are not compatible with 64bit processors. I would like to know whats a good program to use for safe cleaning i used ccleaner in xp but with this OS it doesnt work quite well anymore. When i tried to uninstall Office 2007 home student 2007 it gave me errors and as well norton internet security 2007 gave me more errors and i was using its add remove feature doesnt work. Do you know of one or many i could use with this kind of vista 0S 64bit. I dont want to mess this up again. I have tried tuneup utilties 2007 2008 and now 2009 to its max. Scared to use the registry cleaner please help ok i want something a novice user could use thank you and yes i have tried pc decrapifier as well maybe some nice tuneups or tweaks you could give would be great thanks
