I have happily used Ccleaner for years on my PCs and encouraged my students to do the same. -- Now I also use a MAC with Parallels Desktop installed so I can run Windows applications on the MAC. -- QUESTION: I want to protect the Windows operating system on the MAC and keep it clean. Has anyone installed Ccleaner to Windows running under Parallels Desktop on a MAC? I'm about to download Ccleaner, but thought I'd ask first if anyone's had experience with this. -- Thanks, Crystal
