How unfortunate that Microsoft have to dump all their advertising is some foreign langauge which I don't understand. They fail totally to give one reason for upgrading (or is it downgrading?) or to tell me what the PC requirements are.
I have a phone running on Win10 and it is a catastrophe - they wouldn't even tell me what the icons mean and some of then have changing effects. If fact the company simply cannot be contacted and to get to one of their "experts" I would have to drive about 1000 miles.
