If so, would you recommend and free ones?

ok so iv run a registy clean up and it tells me i have like 850 errors!!! and o of course all the free ones only fix the parts that are ok…… so anyways i really need a free one that you just download run and fix! thx alot guys

i dont know what to do at the moment i only use ccleaner. I know if i run reg cure netcom3 or any other it will find errors but doing this could destroy my registry. So i was thinking do i just use the free ones and if so witch one do i use. easy cleaner . Eusing Free Registry Cleaner . or do you recommend one that you know one that you 100% trust free or purchase can you help thankyou for all honest repilys on this subject

And WHY/REASON for your choice????

Thank you:-)
Oh yeah…please only list FREE ones if possible:-)
Thanks for all your answers so far everybody:-)

My computer is really messed up, and won’t stop freezing out of nowhere! With research, I found out that I have to clean out my registry and i downloaded a bunch of scans like: Regcure
However, the scans spot my problems, but I can’t fix them because I have to pay. I tried looking for free registry cleaners online, but all the ‘free’ ones are just scans x/ theyy don’t fix the problem without me having to put a serial keyD:

Are there any COMPLETELY FREE registry cleaners?
