Best Settings?

I want to keep my computer as clean as possible but I am unsure what the settings are in the attached screenshot and if they are safe to check off or if that may cause me problems.

I am usings Windows7 Home Premium

Internet Explorer 9

Thanks for any help.

Lots of info here

Perhaps stick with the defaults that came on ccleaner install for now until you have read up on things..

That link doesn't mention the Environment Path choice in the Advanced section.

What does it do?

removes all non-standard (user/software created) environmental variables. Best to not check things in advanced section unless you know you want it clean, in my humble opinion.

Thanks for the info. :)
