I have PC tuneup unlimited and have just installed it on a Windows 7 laptop. So far it has worked fairly well albeit slowly. However it states I am 41% optimized with background and startup programs. When I click to show, the screen goes blank for a while and then shows a constantly circling arrow which I left for over two hours and it didn't change. I have used this program on my other laptops without problem and I have another hard drive with Windows10 on it which I can swap into this laptop. It works fine there so what has gone wrong please?
