Hi, Many moons ago I bought the Windows 7 Retail edition. If I am correct I can have it installed on one PC at a time but the license is valid forever. A hypothetical question, as it is upgraded to Windows 10 if I were ever to build a new PC can I uninstall the OS and then install the original Windows 7 and purchase a upgrade to windows 10?
if you build a new pc - just install windows 10 on it and reactivate it. If you've done an upgrade you have a license attached to your account and you can change the hardware on that, Ive done it a few times.
As stated above. Just install Windows 10 from scratch with the code you installed 7 with originally and it will activate with no head aches at all
I got to try that when I get home, I replace motherboard and lost my activation, did want to go back to 7 and didn't want to pay for 10. Been running with the activation notification in the bottom left corner for a couple months now.
The advise on the Microsoft's website didn't help, as I do not have a Microsoft account and thus have not linked the digital license to my account. However, as Behemoth pointed out, using my retail Windows 7 license key allowed me to activate windows 10 on my new system. I assuming this only work since I perviously migrated the license from 7 to 10.
