Yup, Windows 10 LTSC here. It's a lot faster and smoother, but I'm already transitioning to Linux on my other boxes. Will probably move before LTSC runs out as well.

edit: I realised I overplayed how much faster and smoother it is. compared to standard win 10 or 11. Example being my login screen sometimes struggles to come up when the computer is locked (work around double mash CTRL-ALT-DEL)

I have a Surface Book 2 which was insanely fast when I bought it. Its pretty vanilla, I dont like to tweak Windows often it usually feels like it degrades, its been sluggish the last two years or so. Idk what Microsoft did but used to be vanilla Windows was performant enough, they must have fired their performance guys? Idk
