Installing and running CCleaner

CCleaner for Windows CCleaner Windows Bug Reporting
1

I read about CCleaner in Readers Digest and I am trying to clean up my computer. When I tell it to analyze, it shows a large amount of stuff that needs cleaning. I don't know how to keep something from being deleted, i.e. it says Windows 7 - but it doesn't say what part of it needs to be deleted. Help please.

Thanks, I did that and that's when I saw stuff that I wasn't sure should be deleted but I couldn't figure out how to mark them delete or don't delete.
