Is Drive Wipe available on all versions except free or trial? (tried it with free and the C drive is grayed out) I'm getting ready to sell my windows 7 computer and read a review that said CC Cleaner's would do the trick. Since I will not have my Windows 7 computer anymore will my full version transfer to my Windows 8 duo for that download to be full version (I'm running free right now). Thanks for clarifying these issues for me.
