Back when the windows 10 update was free I updated all my laptops to win 10 and then rolled them back to 7 or 8.1. Now I have one I7 machine 8.1 that I am thinking of of going to windows 10 as I would like to use windows INK.. It was my understanding that you had a permanent digital license to upgrade in the future. Now I just read that it was only good for a year. Ture or False? Thanks for any Info....
