I have purchased a new PC and I would like to transfer Windows license from my old PC to the new one. I am using Windows 10 (which was upgraded from Win 8.1) on my older computer and is activated with a licence linked to my Microsoft account. On my new PC, I have installed fresh copy of Win 10 using Media Creation Tool. To activate Windows on the new PC, I attempted the following, but have not deactivated Windows on the old PC (deactivation procedure described here)-

Settings > Update & Security > Activation> Troubleshoot> I changed hardware on this device recently> Logged into my connected Microsoft account > This is the device I’m using right now > Activate.

After performing the above, I am unable to activate Windows on my new PC. Please help me with the following-

  1. Do I need to deactivate windows on older PC first?
  2. Does Microsoft entitle users to transfer licenses to new PC?
  3. Is there anything else which I have missed out?

If this helps- slmgr -dli gives the following

  • “After performing the above, I am unable to activate Windows on my new PC.” - Please provide details. It should be as simple as entering the product key on the new computer – Ramhound Nov 18 '19 at 12:46
  • You should be able to remove and de-activate the device to transfer the license via your Microsoft account > Devices > click on applicable device > More Actions > Remove <device> – JW0914 Nov 18 '19 at 13:06
  • @John The screenshot shows "retail". – user931000 Nov 18 '19 at 13:45
  • Then you can move the license (but only operating on one computer at one time) – John Nov 18 '19 at 13:48
  • I have deactivated windows on the older PC, but that did not helped. I have asked a followup question at superuser.com/questions/1503910/… – pkj Nov 21 '19 at 11:08

The process was rather simple, but I could not find the solution anywhere on the internet. The process detailed on How to transfer a Windows 10 license to a new PC or hard drive did not helped me.

I contacted windows support and they told me that I can activate Windows 10 on my new PC using the Windows 8.1 key which I used to upgrade to Win 10; this worked for me after deactivating Windows 10 on older PC using slmgr /upk.
