Fyi...upgrading an 7/8x to 10 or clean installing Win10 using an 8.1 key(another upgrade route from a qualifying o/s - 8.1) using the MCT tool provides a digital entitled license - you will not be issued a re-usuable Win10 product key - i.e. upgrades to Win10 do not receive a product key. Your Win10 digital license is tied to the hardware/device on which Win10 is installed with your license stored online in the MSFT Store. If you need to install Win10 again (reinstall or clean) on that same device the digital license will permit that reinstall/clean install without the need to enter a Win10 key (a Skip product key option is available) and activate Win10 after athe digital license is validated for that device. I am not clear if you need two separate Windows licenses for dual booting w7/8x and w10, or you can re-use the same w78x "old" license that was "upgraded" to w10. Actually, if you dual boot, you are not going to use the same license at the same time. I haven't seen the answer to, "does microsoft blacklist your old key when you upgrade?" I think that's the critical parameter. I don't believe that happens. Here's why. I have a desktop which I upgraded from 8.1 Pro. The upgrade went well, however I had many display irregularities due to an old video card, so I decided to revert back to 8.1 Well, the 30-day rollback didn't work. It told me that the backup files were unavailable (they WERE present). After trying a few work- arounds, none which helped, I reimaged my machine back to its 8.1 Pro state just prior to the Win 10 upgrade. That was over 2 months ago and my 8.1 system still is registered/genuine. Just a data point to consider... That's how it's intended to work. Upgrading replaces the prior qualifying o/s license (in your case 8.1 Pro was replaced with 10 Pro). When you reverted back to 8.1 you no longer were using W10's (digital license and activation) thus un-replaced 8.1 permitting its use after 10 was removed. The above, for that same device, does not preclude your ability to return to Win10 at a later point in time - upgrade again during the 'free upgrade Window using Windows Update or MSFT Media Creation Tool media, or clean install during the free upgrade windows or after the free upgrade window using the Media Creation Tool media. Optionally, during the free upgrade window one could clean install 10 and use the 8.1 Product key (retail or OEM). The presence of the GoBack item is MSFT's method of assuring that you can revert to the prior o/s and un-replace the prior o/s - it does not matter if you GoBack within the 30 days or use another means (recovery media, image, reinstall using media) to rever to the prior o/s. Winston... One thing I don't get is that I never uninstalled Win 10, I just reimaged over it. As far as MSFT goes, my Win 10 license was never inactivated, it just has been idle. What prevents me from upgrading to Win 10 and using my 8.1 image on another, similar machine? Because that seems to be little different that what I did. |

Where did you get the 8.1 license/key?? If it came preinstalled, as I understand it, you got a generic OEM key. They can't invalidate the Dell generic key??? What am I missing? |
