Easy exemple, my GF's laptop was full of bugs and various programs were crashing. Update to 8.1 did the trick.
Of course I do not base this on one experience, actually tried win8 when I upgraded my desktop, before going to 8.1. Same deal.
Anyway I think I'll give them a few updates before I upgrade to 10.
Weird. Worked fine for me and a lot of other people. Had it on quite a few machines around here and no issues bar the Realtek and AMD issues, both of which were sorted out eventually. When it was the latest Microsoft OS it was a good one once you got over the lack of a Start Button/Menu.
Of course, going back to it from 8.1 you see what improvements they made in 8.1 (and it's not just the addition of a Start Button, there's other stuff too such as much-improved searching in 8.1), but when I used 8 as my primary OS before 8.1 came out it was a good OS.
I must admit that the marketing about Windows 10 being a 'familiar' and 'simple' experience is definitely not the first time I've heard about a new version of Windows being 'simple to use'...
...but that was back in the days when I had to pay for it!
And yes I know they've marketed just about every version of Windows with that same terminology but it still makes me smile.
(It's been a long time since I've used those discs by the way!
