Which system utility do you use to clean and your computer

I use winxp manager for windows xp and vista manager for windows vista to clean and optimize my computer. It has lots of features like cleaning the junk files, cleaning the registry , tweaking the operating system, optimizing the computer , fixing minor problems of operating system etc and many more. So with it installed I do not have to look for other utilities.

I use the disk clean, defragment and from the start up menu , I type %temp%, which contains the temporary internet files that were stored and delete them. Have a nice day!!!

I am using CCleaner to clean everything on my computer. Then i would run my Spybot then do some scanning. Then do some Scandisk. Restart then my computer is good to go. I do like once a week except CCleaner which i'm using before i put my computer to rest for that day. I don't really use other stuffs because based from experience, i damaged my computer for using untrusted software.

I have tried CC Cleaner which is free to download from their website. It prompts you what files to delete from unused applications, internet history, temporary files, saved passwords, cache, registry trash, etc. Among other cleaners, its much faster and no adwares. Just be careful in choosing what files to delete unless you have a backup!

I use disk cleanup and defragment.

A combination of CCleaner and Dustbuster XP is what I'm using to get rid of all craps residing in my PC... Defraggler, is what I use mainly to defrag & redefrag iot again w/ Windows default...after that, I put check disk error in running mode after a restart... It is really useful & effective.

I use disk clean up source to clean my computer .It will help us to have some space.
