*"Anyway, like I've said.  I don't use a registry cleaner to fix spyware issues"

A slowed computer sound a lot like viral/spy symptom, and I kinda doubt the average person would ever know the difference...

Not to mention sitting through oodles of Windows updates and such before they can even re-install anything.  

*You do'nt need to install the items to use Windows.  If anything is direly importatn you'd know, else there is nothng there that has warrented a new version of WIndows.  The updates instal between when you've Shut Down, and when the computer actually turns off, usually over night!
