Literally never had the need to disable defender or change anything about my Windows install.

This doesn’t mean anything if you’re not saying what hardware are you running. I saw what was happening in task manager no matter how much time I gave it. I don’t have time to debug a product I paid for, especially if the free alternative „just works”.

Driver support is far better on Windows than Linux.

For things that Linux supports (which is most of it and the older the better) it’s a much better experience since everything just works out of the box. You might have trouble with bleeding edge hardware but in year or two stuff gets done and keeps working. You might encounter issues on some cheapo laptops with broken ACPI implementations but those are just trouble in general.
