Hello, I have a fairly new PC that I build last year. I'm using Win7 ultimate. Everything works perfectly. Windows 7 support from microsoft is ending Jan 2020 and I'm hoping my pc will last longer than that. I've tried Win10 on a different machine, didn't really like it, but I know I need to upgrade sometime, and I want to take advantage of the free Win10 activation offer before it expires this summer. So, I was thinking of doing this: Make a disc image of my current setup with Win7. Upgrade to Win10, keep it for a week, let it activate so my system information is stored by microsoft. Reinstall Win7 through the disc image. Install Win10 in a few years. My question is, do you think that this would work? How long does microsoft keep my Win10 activation information? Thanks.
