Valve's monthly survey reveals that almost 45% of Steam users on PC are still using Windows 10 even with the sword of Damocles hanging over them

There are still people so powerful they manage to use Windows XP in this day and age. My intuition says most people will be able to use Windows 10 for at least one more decade with minimal issues, after that it will gradually become trickier, but it will still be usable even in 20-30 years with advanced hacks if humanity doesn't go extinct by then.
