It will often replace drivers for ticket printers, barcode readers, scales, etc. The auto driver update needs to be disabled to prevent windows from installing 'better' versions of perfectly good working peripherals on my clients and break them.

Especially on weaker machines, the difference is very noticable. That service can and will eat up a ton of resources and is always running. I don't give two shits about what Microsoft collects through telemetry, i trust it to be harmless but i care a lot that it may slow down the PC. I use it mainly to disable telemetry (this is green and there's a few) and driver updates through windows updates (this is yellow). The green profile never disabled anything that would break windows, that i noticed, i consider it pretty safe. I've been using it for years because it's damn convenient. But even if you do switch off something you don't want to, just go there and switch back. It is still recommended to check each option to see how it is actually affecting the system. That one is pretty safe and won't turn anything major off.

They also have profiles you can apply, for example, theres one that will only disable green switches. Green is considered safe to disable without turning off something core to the system, yellow you might be disabling some function you don't want to and red is probably better left alone unless you really know what you're doing, as they can impact the system. They categorize every switch with how 'dangerous' by color it is and explain what each does. Shut up 10, is actually really good at this. You get to choose what you want to do, you won't automatically break anything by just opening it it. It's reliable and has everything in one place, all organized, explained and toggable by a simple switch. Even it there's a switch somewhere on a settings windows, Microsoft loves to rearrange options to elsewhere across Windows updates. But they're often obscure to do manually, like inserting a registry key somewhere down the reg tree. It is true that all this does is switch on/off options that already exist in windows. All of this can be true but it's not that linear.
