I use AML’s Free Registry cleaner. One day after cleaning the registry keys up, I could no longer connect to the internet. After restoring the back up I made, I could connect again. What are some keys that are responsible for internet connections so I can put them on an ignore list?

I need a free registry cleaner. The registry cleaners I currently have are:

CCleaner
Eusing
Abexo
Advanced Windows Care
Tweaknow
AML

Yes I know I have a lot, but each one finds different errors, so I guess I have more errors on my computer (plus its gotten really, really slow and I have 3.5 GB RAM and a 3.2ghz dual core processor and my other windows 98 computer runs faster than it).

So anyways thanks if you know of any other free ones!
