I upgraded several months ago from my Surface 3 to the Surface Pro 4, but I donated the S3 to the nonprofit where I work. Now it's come to my attention that when we try to boot it up, it takes us to a screen that says our version of Windows has 'expired' and that we need to use a recovery USB to boot it up. I tried to boot through a USB but nothing changes....it still brings up the message that Windows has expired and to try to boot with a flashable USB. First, I don't know how Windows could "expire," since I never pirated any version of Windows. I had W8 and then when they offered the free upgrade to W10, I did it. More importantly, is there a way to get past this Catch 22?
