Hello, I've recently had some troubles with moving between Win8.1 and Win10, and decided to stick with 8 for the time being. When I got back there, I was met with two strange things: My internet explorer homepage is Hao123 And my taskbar menus have different backgrounds to the typical, including a larger Pin icon- see below. The homepage issue I fixed, but the menu background one I was not able to. I decided to try a clean install, and when it completed the problems had reappeared. I believe there is a piece of rogue software, persisting past multiple reinstalls somehow. I am tempted to completely overwrite windows with another OS, before reinstalling Windows from there- is there a less over-the-top fix?
