The pc I'm working on is advanced in years... Already more than 8 years old, and still working fine. (It's an Acer, and must not have been built on a Monday...) I'm lucky with this one. The two before that were gone in less than a year. The first one got caught in a fall of my mother, so I bought a new one and that only lasted about a year. Afterwards I got the one I'm working on right now.
Months ago, I read in the newspaper that Windows 10 wouldn't work on a computer older than 2 years. Well, I've just installed it and it works fine!
Of course, I'll still have to get used to some of the new functions, but then we're not too old to learn, even when nearing 60!
