Doing a clean install of W10 involves using my W7 product key. What happens if I want to return to W7 with a clean W7 install?
I'd guess there will be activation problems because the W7 product key has been used for W10.
Likewise what happens if I want to return to W7 using a disk image?
I haven't seen answers to these questions. And with the MS push for W10 I'm at least suspicious of returning back to the prior version. All of this is tied to the free upgrade where the prior W7/W8 product key becomes the W10 product key.
The product key for many newer computers is embedded in ROM. In those cases you don't need to do anything to get a fully authorized installation regardless of whether you are upgrading or going backward. To check to see if your computer has an embedded product key you can use this tool: NeoSmart
