I'm close to a similar point, my PC has been Linux for a couple of years but my old surface book has been on windows 10 (with some 6 year security update thing that was mentioned during the time Win 10 was dropped).

The main reason I haven't dropped it is that I sometimes use it for work or uni, so compatibility and other people being familiar has been a priority but I've graduated and got a work laptop so it's probably time to drop Windows outright.
