If you own a Windows 7 or Windows 8.1 PC, you likely know that your machine is eligible to get a free upgrade to Windows 10 when it launches July 29. That free upgrade offer will last for a year after that date, but which Windows 10 SKU will you get for that free upgrade? Microsoft has revealed that information on their Windows 10 specification page.
If you own a PC with Windows 7 Starter, Windows 7 Home or Windows 7 Home Premium, Microsoft will give your machine an upgrade to Windows 10 Home. Owners with Windows 7 Professional and Windows 7 Ultimate will get Windows 10 Professional.
Windows 8.1 and Windows 8.1 with Bing users will get Windows 10 Home, while Windows 8.1 Pro and Windows 8.1 Pro for Students owners will be upgraded to Windows 10 Professional. As Microsoft has previously announced, owners of Windows RT devices like the Surface RT and Surface 2 won't get a free upgrade to Windows 10, although they are supposed to get some kind of update that will add some of Windows 10's features.
