Ccleaner and Tuneup utilities2009

[MackDaddy]

Ace Utilities is very good, it cleans the usage tracks and it is very good as well for wiping the free space

While having it set for Pseudorandom Data which is 1 pass, for every 100 GB of free space it takes about 6 hours to secure over write the free space

If you have it set to the higher passes then it could take days to weeks to complete, because of that just select Pseudorandom Data, they haven't been able to recover data from a HD with a electron microscope for about 10 years now because the information on the platter is much more dence now days, because of this I believe that the Pseudorandom Data setting will be enough

CCleaner and Tune-Up Utilities. Eusing Free Registry Cleaner isn't so bad, either.

Have been using Your Uninstaller's 1-Click cleaning , amazing the temp files it finds .

Perfect match with CC and if trying a lot of software like me its got a great regcleaner .

Yep, Your Uninstaller is really great and you have a lot of other options too.

I tend to use Registry Mechanic when I was still using xp. Now I use CCleaner as Registry Mechanic isn't supported on my new 64-bit vista OS.

I use CCleaner the last three years.
I have never had a problem with my PC.
