Just like 10, windows 11 reserves a lot of ram, but it’s not really using it. When you need more ram it will unload a lot of things. It’s just sometimes too damn slow at it, especially on a device like a surface which has pretty pokey hardware. (Despite on paper it supposedly being much better)

You can try those de bloat scripts. Instead of waiting for windows to unload the shit you can just stop it from loading in the first place. On a VM of mine it made a pretty big difference, but on my SP7 it seemed to not work(?) it didn’t seem to do much. I’m generally not a fan of those though because they tend to break a lot of things. Like one of them turns off hibernation which is a huge no no on modern standby devices.
