If you are using windows 10 I would hold off for a bit on the reg cleaner. They have some work to do with this. I just spent the last few days trying to figure out why none of my updates where downloading including Microsoft Store. I thought it was their fault but after digging a little more I figure out it was ccleaner that ruined my reg beyond repair. I have never had a problem with this program and it has always done a great job but as I said before it needs some serious updates!!
