Windows 10: "We can't reactivate Windows on this device. Try again later" - Problems while transferring...

I have an old and now slow PC with a Windows 10 pro license. As a replacement I've built a new PC with new hardware and am trying to transfer the license to the new PC. I still have access to the old PC, I just won't be using it anymore. The old PC has the Microsoft account linked to it, so the license is linked with the account. I am also using the same Microsoft account on the new PC.


In the troubleshooting process Settings > Update and Security > Activation > Troubleshoot, I select the old PC, press Activate, and then I get the message that Microsoft wasn't able to reactivate windows, and tells me to try laterquote in title. How can I fix this issue?

Edit: Forgot to mention, the old PC DOES have a retail license.

Does Windows 7 require reactivation if...

He is using AMD already. He wants downgrading to AM3. Don't know why??

If you change HDD + RAM simultaneously, Windows 7 needs to be reactivated. Only HDD cloning shouldn't require reactivation. As you are changing mobo + HDD (prehaps RAM upgrade too), you will surely require reactivation. If you have genuine license, you should reinstall OS (you might use Windows Easy Transfer). If you don't want to reinstall, you need to uninstall HDD, interfaces/system devices, and numerous other drivers (USB, HID, Portable devices, etc.), else your OS will be unstable.
I will highly recommend to reinstall Windows 7 and enjoy your migration.

A simple trick might be like this to avoid reactivation:
1. Clone your HDD first and boot into Windows
2. Use it for at least one week
3. Replace mobo only without any other hardware change/upgrade and boot
4. Use it for at least one week
5. Do any other upgrade (RAM, Graphic card etc.)

Don't do two simultaneous downgrades/upgrades to avoid reactivation.

Then why does it say fs/ft i7-920 in his tag and he wants to downgrade to am3 system? to go from a am2/2+ to am3 isn't a downgrade last time I checked

 

windows 10 reactivation after hardware change

I just changed motherboards, and When I follow the the steps listed in the "reactivate windows 10 after hardware change" support page, it gives me the message "unable to activate windows" message after I sign in and identify my device,
with no error code, just a subheader that says "can't activate windows 10 on this device, try again later."
