Windows 10: Transfering windows 10 product key to new PC device

Hi,I recently got an entirely new PC and have been trying to transfer my license from my old PC to the new one. I have tried countless methods recommended on other forums but am still getting nowhere. I have checked to ensure I have a retail key and that when activated on my old PC it states it is a digital licence linked to my Microsoft account and used slmgr.vbs /ato and /dli to obtain the system information and product key. I am using windows 10 home edition core. I have ensured my emails are matching for my windows login under settings>accounts>your info as I do have two Microsoft a

Transfer of product key

Hello.

Whoever told you that you need to "deactivate" is wrong. Go here for actual steps on transfering the product key over:

Simply put, you just need to transfer the license over. you do not need to deactivate first.

For more info, i suggest calling MS support about activation issues.

Is Product Key Transferable to New PC?

Hi, if your original license was OEM, it cannot be transferred to a new PC.

If it was retail, it can be- as many times as you like. Which was yours? That's the - er - key question.

There is no product key for Win 10 in the same way as for previous editions.

I'm not quite sure if you're referring to a completely different PC, or simply reinstalling Windows on the same PC. If the latter, activation should be automatic. It may be harder if you're making significant hardware changes.

If you have a retail key, please see:
Clean Install Windows 10 Directly without having to Upgrade First

Uninstall Product Key and Deactivate Windows 10

Activate Windows 10

Finally, if you're confident that you have the right to Win 10 on your target PC and still have difficulty, you can contact your regional MS activation centre.

 

Need help with transferring Windows 10 to new PC

*Nevermind I figured it out. I just bought a license key for $29.00. Thx though.
So my friend asked me to build him a new computer for work. The last one I built him was during the windows 7-10 upgrade grace period. I used to load windows 7, use windows loader to put in a product key, activate it, then upgrade to windows 10. Now that the grace period is over, and I'm working with new hardware, I was wondering if it is possible to install windows 10 from an already functioning computer that operated on a sata SSD to a new computer with an m.2 nvme SSD, using just the product key from the current windows 10 off of his computer. I use a program that grabs the product key called ProduKey.
Should I do a fresh install of windows 10 using his key after deactivating it from his current PC , instead of cloning drives correct? It would be nice not to have to pay microsoft $200 for windows 10 if he already has it and plans on not using his old pc anymore.
