When I did a registry scan with CCleaner the other day there was the usual unused file extensions to be fixed as well as one I have never seen until now. On the list it says Problem,Data,Registry Key. Even though it is ticked and should be fixed with the other issues it never is. I did another scan tonight and came up with 3 unused file extensions and this.I clicked on fix all issues but this one won`t go away.The laptop seems to work fine and I have not had any problems. I was wondering if anyone had any ideas?
