I'm reading the press about W10 and I've so far read two bad things.
1. someone kept his porn in his Pictures folder and W10 helpfully displayed it on the screensaver by default...
2. W10 does not play DVD's so you either buy the capability from MS or download an app
The second article is simply old news. Neither did W8 and that theme is continued. The answer is really simple. download VLC media player and use that. It's really excellent. The article did say that too but the title was misleading. I've been using VLC for years now and for a free app which is 28mbytes, it's absolutely excellent. It plays DVD's and Blu Ray without issue. Plus almost every downloaded media file I've ever tried running on it.
So I wonder. Is W10 better than expected. Within 24 hours there were 67 million installs. OK there were issues and continue to be issues. But, in general, it's been pretty good.
