I have Windows 10 Home (v. 1809) on a DVD and I have a product key for it that I can use if necessary, but I would prefer to upgrade from Windows 7 if at all possible to save the 'burden' of re-installing all the applications. I hope someone will know how to do it, other wise this nice little PC (which I mainly use when away from home) will soon have to go to the scrap heap!
