I think tuneup is great you have to try

Remember chaps, If you are gonna be cleaning the registry to always back it up.
I can remember a friend recently stuck on some great reg cleaner he found that got rid of hundreds of problems it found and he was, wow this is a great program.
Then he rebooted and got the NTLdr not found message
And i had to show him how to reboot his dead PC.
Even though some programs find stuff, some..not all are attached to other running programs.

This is very true, a few years ago I tried the program evidence eliminator and I had it (clean/fix the registry with the default settings) on my computer and it made it crash

Even though I don't use evidence eliminator anymore I haven't used the (clean/fix registry function in any clean up programs since just because of my experience with ee)

I don't know if it would work ok with Ace Utilities to use the (clean/fix registry function) because I never tried it will Ace Utilities, although I use the overwrite free space function in Ace Utilities and it hasn't caused any problems yet

I also use the clean up usage tracks function with Ace Utilities

CCleaner is good for usage tracks as well

I find SpinRite works best for my uses

[darkstate01]

Yeah i've used spinrite a few times. If you have a HDD on its last legs spinrite will fix it, Takes a long time doing it though but its better than buying a new one.

TuneUp 2009 , CCleaner

Cant forget to defrag after downloading tons of gigs of content. I found that O&O defrag is pretty good especially when doing alot of things it has a stealth mode that uses less resources to defrag, but it also has 4 other modes for defraging.
