Hi guys, I need some advice on this. I am fairly new to this so please bear with me. I downloaded the new trial version of sktools from pocketgear and I was wondering if I should delete the invalid registry entries/values found by the the software? Or should I just leave it alone?? When I use cleanup it doesn't delete the invalid registries so I'm wondering if it can be only done manually or something of that manner.
