If you own an Xbox one, you can stream the game to your PC with windows 10!
Windows 7, 8 & 8.1 users get a free upgrade to windows 10, you only have a year to do so.
Windows Phone 8 users get a free upgrade to Windows Phone 10.
Microsoft confirms: DirectX 12 will be a Windows 10 exclusive
One point update that Anandtech disclosed as well is that Windows 10 and DirectX 12 will be bundled together — D3D 12 will not come to Windows 7, 8, or 8.1. The free upgrade offer on Windows 10 will doubtlessly blunt a great deal of criticism that MS would otherwise have come in for, but users who can’t upgrade or simply don’t want to won’t be happy.
Essentially, if your copy of Windows shows as non-genuine, it will remain in that state after the upgrade, however there is no information on whether windows will expire after some time or not. According to the article, Microsoft says that there will be means to address the non-genuine state of Windows via the Windows Store.
