regcleaner and C07ft5y (WXP-Home)

[panic]

Hi! Two questions - I am back to using RegCleaner instead of jv16 (because of the date cutoff) and I get three lines that I don't understand. I can't find two of the files on my hard drive manually, and I can't "start - search" and find them either (WinXP is everywhere, I can find it ;)). The same file name for two currently nonexistant items, and an os? Baffles me...

The WinXP one seems wise to keep, but the other two? One was a game (uninstalled), and I don't remember the other at all. In the jv16 list, there was a red dot on the left; RegCleaner does not highlight them at all. What causes them? Can I delete these? (<-- two questions) Thank you! :)

I can only inform you of what I know. I will Quote you what I know “Its default value is "SafeDisc RefCount" and it has one subkey called "WinXP". I even had it after completely formatting hdd and fresh installing XP. So if you're being watched, all the data gathered about you goes straight to Redmond, Washington;” “GhostRecon =Ghost Recon= Xbox;” Hopefully others with more information will post and we will bother know more.
As I posted, using j16 1.3 remains my choice until something better comes along.
