Microsoft officially ended their Windows 10 free upgrade program on July 29th, approximately a year after the operating system was released and just days before the Windows 10 Anniversary Update arrived. Windows 10 is now running on 400 million active devices as of September, thanks in no small measure to that free upgrade offer.
There are still a lot of Windows 7 and 8 PCs out there, however. For those that did want to upgrade but didn’t get around to it, there are still a couple of known ‘loopholes’ to get a free Windows 10 upgrade which Microsoft hasn’t bothered to close, even months after the offer formally ended.
