Hugo got the Windows Anniversary update and he finds that the PC runs at 100% all the time and that it runs hotter. Leo says that has been a common problem for many users, and once you've upgraded to a new OS from an old OS, it may inherit some issues. Leo advises using Microsoft's Media Creation tool and backup his data, format his hard drive and reinstall Windows using the Windows Install he just created. That'll definitely fix it. He can think of it as Spring cleaning. There could also be some bugs in it that is causing some services to run even after he's closed a program out. It could also be malware. But reinstalling Windows should fix the entire thing. His PC will run faster, too.
