i have searched online for free registry cleaners, but every time they say they are free, it scans my computer then when it comes to fixing it, it then ask to upgrade and stuff where i have to pay! Does anybody know of any good ones which don't?

What do you suggest

deleted file but some still on pc cant find them but know they r there

I scaned my computers registry from a registry cleaner, but I m in doubt that is it really cleaning the invalid registryies or not. I think that it is not compeletly scanning all registry entries. One more think I create a invalid registry in "regeditor" but it is not showing me that invalid registry. So how i can chk abt this "is my registry cleaner is working fine or not"

I'm still on Windows ME, I have a Kernel32 error coming up and have been told to use a registry cleaner.
Thanks.
