Easier said than done, I tried paring down a bunch of seemingly unnecessary services on my Windows machine and it wound up breaking things in unexpected places.
Did you know that turning off handwriting recognition for tablets makes it so keyboard presses do not cause the lock screen to open to the password textbox, or that it breaks the ability to start typing in the start menu for search results? There's probably a good reason for this, but now I'm way more cautious about turning services off.
I understand the eternal desire for optimisation, but it’s a game of diminishing returns.
Most of the items people agonise over in taskman.exe aren’t using negligible memory and cycles. The software for your RGB keyboard is probably less efficient. Kill Teams, browsers and anything edge that actually handles content, and you’re probably at 95% capacity.
it's not so much the running processes, as it is the unpredictable nature of scheduled tasks which do things that just suck performance away from games. those things often run with very odd priorities and very odd schedules or triggers. Also, when games are run and windows doesn't really get to see the mouse move normally because the game has captured it and controls it, windows sees this as "idle" time in some ways, and will handle background activities via the task scheduler. in any use pattern that is not gaming, this is the correct behavior.
a windows OS mode that is single user, networked, and meant for limited use (so background housekeeping windows tasks run after you exit or reboot out of this mode) would be pretty ideal, not just for raw performance (which would be measurable, but not the main goal) but to avoid apparently random decreases in performance due to Windows deciding to do something, or suddenly needing to deal with an authentication request dealing with mapped drives, or something.
Fyi Windows does have a game mode that will do some of those things.
If you want to get super crazy, I'll boot a second copy of Windows off of a vhdx file that's stripped down if I want extra performance.
With a little bit of work you can even clone the sid of your main os, and symlink most of your existing files and info, so it's almost identical to your main OS.
Calyp.to's guide is one of the best I've seen for stripping windows down to reduce latency.
