When's the last time you sat down and thought about how many apps automatically launch whenever you fire up Windows 10 on your desktop or laptop? You probably can't remember, because it's not really a thing most people do. But you should, because you don't need a bunch of unnecessary apps eating up your system's resources for no reason. If you have an underpowered PC, you're only making your situation worse. And, at minimum, having a bunch of background apps is going to make Windows 10 take longer to load.
