I could not tell you the last time I had Windows in the home. I would guess around 2013. After then I kind of went (almost) 'Full Stallman' - I had been moving that way for a few years already.

The only Microsoft product I have is an old Xbox 360 that was updated once and then left permanently offline.

Side story - I remember in late 2001 when the 1st Xbox was coming out and I was in a retail store. There was couple looking to see what consoles where around and what to choose. The husband saw the Xbox and the Microsoft name on it. "I'm not supporting that thing! They have made my life a living hell, Mark my worlds they will do anything to dominate the market and I do NOT support that!" Seeing how they are trying to still buy their way to success, his words ring true today.
