And what about rogue services that come with the OS itself? Things like Windows Update, Windows Defender, the Phone app thingy, diagnostics policy service, the Xbox game bar or whatever it's called, the .NET optimization thingy and a dozen other things that like to wake up randomly and start consuming resources whenever they feel like it. Most of these things you can only disable temporarily, if at all, without resorting to dubious 3rd party tools.
