I pulled my ssd out from old computer, which contain the windows 10. I erased all the data beside windwos 10 itself before unplug it. I did research before, and check it by command prompt which my key can be transferred. Now I use another ssd as my system drive, and I can\’t find a way to recover my activation key. What can I do now?
dota2er : Yes, this is whole new system. No, it is not activated. My win 10 is upgrade for my win 8 which I bought from a market. Right.For an Upgraded Win 10, you should have linked it to your MS account before swapping hardware.If you go through the Activation Troubleshooter in Settings, what does it say?
