The new task manager was the only thing I found compelling about 8/8.1
There really is a lot more there, and 10 adds that much more.
Client Hyper-V is more supra-OS, and it's not necessary to use Win8+ to install a hypervisor.
But you've got to admit its pretty cool to have it bundled with the OS. Its way ahead of virtual PC; and works well with Microsoft Hyper V server. (with or without "Windows Server").
. And as mentioned above, multiple desktops have been a part of Windows for a while, though must be enabled through external tools.
Making it an officially support part of the OS means that
- a lot more people will actually use them
- you can sit down at any computer and they'll be available
- applications developers will actually support them properly because when push comes to shove its fine for your program to not be compatible with some obscure 3rd party power-user shell extension that some random user is saying conflicts with your application - like dialog boxes showing up on the wrong one or some other annoyance. But not working with a core feature of the OS? You'll actually fix it.
As for what else 10 has... DirectX 12. Resizeable (horizontally) command windows; builtin antivirus that is adequate for me, better multi-monitor support, the aforementioend multile desktops, the netflix app... for some people (not me) the xbox app stuff might be pretty compelling too.
I'm not sure I'd pay to upgrade from 7 or 8.1 to 10, but a free upgrade from 7 or 8.1; it makes decent sense.
Or on a new system with a bundled OS, sure I'll take it.
I'm certainly not planning to dig my heels in to stay with 7. And I'm really not sure why you claim you will... at worst you've said there's nothing in you 'must have' .. and ok... I accept that. But you haven't said what it has that you 'must avoid' either. And given it'll be free, and it's at least a slight upgrade, why not?
