Deal DetailsLast Edited by annie930ny July 29, 2016 at 10:21 AM
If you upgrade to Windows 10 today and allow it to activate, your current computer will have a digital entitlement stored on Microsoft's servers. You may then use the built-in
recovery feature within 30 days to revert back to Windows 7 or 8.1 . You may then upgrade back to Windows 10 later and your digital entitlement on that machine will activate Windows 10 again. If you make substantial changes to the hardware in your computer like replacing the motherboard your digital entitlement may no longer work.
