Regarding 2: That is actually part of my job. 95% Windows, the rest is MacOS and maybe 3 to 5 Linux users (myself excluded).

I wonder what must happen to roll out more Linux in the public sector. There is still software required by scientist of various professions that need a tool only available for Windows. Installing a VM is not an option; too complicated for the average user.

And there is Windows software not compatible with Windows 11. Here is a small chance to use wine, but will the setup be practical and installable by the users themselves? I doubt it and it will put more work on the admins.

I hope at least, that Linux maintenance will be smoother despite the need for compatibility for older Windows software in the future.
