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
Yeah, their performance has gone in the toilet. Recently we needed an old system setup just for group meetings in the office. I installed 11 on it - it struggled, gave up, threw a linux install on for giggles and it's buttery smooth.
