Registry cleaner.
 

I have seen some registry cleaner programs like registry mechanic that seem to work great but... I dont just want it for my personal computer. So something free That i could install on a bunch of computers would be great. Does anyone know of a free one that isnt just a trial? I currently just use ccleaner and it does clean out the registry some but i would really like one that does a better job.

the system mechanic works great and you have many tool you can use. But it's not free

yeah i need one thats free that i can install on a bunch of computers.

CrapCleaner works nicely http://www.filehippo.com/download_ccleaner/

And it cleans other stuff too!

I've never actually had a good reason given to me to 'clean the registry'

it's just a large database, what isn't beint used just sits there until it is, no sense removing something that might be important at a later date.

One more vote for Crapcleaner. I have it on multiple computers and the registry cleaner is simple and effective. It is free to download and use.

yeah crap cleaner is what i have been using. But it couldnt hurt to have a better one. As far as needing a cleaner you never know what could cause problems to need it. People installing random trial software stuff then removing it then installing more crap. Before you know it you start getting weird errors for programs that want to load but cant because they are gone. annoying little things like that. Basicly i just want some simple tools to get the computer back to running like it was brand new without needing to format and reinstall or spend hours messing around with the computer.

You can install Linux. That'll clean your registry ;)
