what is a good registry cleaner and a good cpu/ram diagnostic/cleaner programs. Microsoft uses "uniblue" i believe and its like a program. I can’t afford that. there has to be a good/decent free one until I get the money for a "certified" program, lol. Any help at all will be greatly appreciated

Are there any really good free registry cleaners out there like the uniblue 2009 one. You only get a free scan with that and it removes 15 enteries without you having to pay. I have cc cleaner but I think that sucks. Are there any free ones that do the job, thanks!
NOT CC CLEANER!
I SCANNED WITH CC CLEANER IT CAME UP WITH THE INVALID ENTERIES – THEN IMMEDIATLEY AFTER I SCANNED WITH UNIBLUE AND IT CAME UP WITH SEVERAL MORE SO CC CLEANER OVB DOESN’T PICK THEM ALL UP!

I know how to clean registry using softwares such as uniblue or tuneup utility…………
i want to know is there any option to do it the way by the system such as disk derag u know through system tools
