I’d stick with Win 10 and make sure its fully upto date with the latest 22H2, at least for now, as Win 11 is drought with issues having/had stability issues and as August win 11 update, rendered SSDs and HDDs invisible to users, while also risking permanent data loss, though of course Microsoft denies this, so you’d only be jumping out of the frying pan into the fire.
Ignore anyone that says there’s a work around to get Win 11 on unsupported devices, as Microsoft won’t update and allow security fixes on unsupported devices.
Further more Win 11, also has higher system requirements (bios etc), without these requirements, essential security features such as Trusted Platform Module 2.0 and Secure Boot, will expose the system to security risks.
You’d be brave to go Linux, unless @Rene has time to teach you, I don’t, but a good basic starting point is to get a Enigma 2 reciever.
