All versions can be freely downloaded and installed. It's when it comes time to activate that the truth becomes revealed.The home version of Windows 11 is free and can be downloaded from the Microsoft website.
I have zero Linux experience beyond a few YouTube videos. What do you do when you buy pretty much any current hardware device - printer, keyboard, scanner, mouse, bluetooth device.... Seems like their application software (drivers?) only recognize Win or Mac & that's it? My hardware requests updates, enhancements etc. years later after initial installation. Same goes for many apps. Some I have only run on Win to the best of my knowledge. Or from what I've read, compatibility or version capabilities on Linux is not guaranteed. So that's kind of where the 'choose your poison' kind of comes up. I might look into Linux one day maybe related to CNC, but i was imagining it to be for more or less standalone PC's dedicated to these kinds of apps.I'm so done with Windows
