When I run registry for the first time (once a week), I'm always notified of an "Unused Extension - {". Why does this continue to pop up? Is there any way to determine what program or what is causing this? It doesn't seem to be an issue, just an annoyance.
Do have more than one account on your pc?
I found that cleaning on one account does not clean what is under another account, so do the clean and then switch accounts and do the clean again and see if the entry is still appearing.
there should be zero reason to be doing registry integrity so often. Also I hope in doing so you practice safety (see my signature)
Same registry issue is reported
in CCleaner Bug Reporting
