But I dont use Windows 10 that often - I don’t see the need. I just have it as a backup OS. I have free enough diskspace on my SSD so currently not doing anything.

I did exactly that for many years. And then one day I had something that called for booting to a separate OS, so…

my solution

Trusting Windows with whatever it was still made me nervous, and I crammed an Ubuntu Live USB into a USB port and booted to that. ¯\_(ツ)_/¯
