The first Bay Trail TV sticks and mini PCs were all pre-loaded with Windows 8.1, and so far Microsoft has let users upgrade to Windows 10 for free. I tested the upgrade on MeLE PCG01 and PCG03 last year, and while it took many hours, I could eventually get Windows 10 running on both systems without paying anything.
But Microsoft is reminding users that the Free update offer will end soon:
The free upgrade offer will end on July 29 and we want to make sure you don’t miss out. After July 29th, you’ll be able to continue to get Windows 10 on a new device, or purchase a full version of Windows 10 Home for $119.
So if you’ve purchased a device with a proper Windows 8.1 license, you may consider upgrading to Windows 10 soon. If you do this on a devide with 32GB storage, you’ll get very little storage left, so once you’ve made sure everything works as expected, remember to delete Windows 8.1 backup to free up space.
