@simontatham I recommend just to not use Windows. The frustration with everyone who I talk to about computers always complains about Microsoft products. I did switch to Linux in 2022, I did it hardcore, I chose what I wanted to run and it was Arch btw. I read the wiki and did it. And I can tell you, it isn't very intuitive. As a complete noob, it took me Saturday and Sunday to do it.
@Skye that is a bit difficult when you maintain a piece of primarily-Windows software!
I mean, yes, I _do_ do most PuTTY development on Linux, because most of the complexity is in the cross-platform code anyway. But testing and developing on Windows is still necessary some of the time, either for mysterious bugs, or changes to the GUI in particular.
