Windows 10: Can't reactivate Windows 10 Pro after a hardware change

Yesterday I upgraded my CPU, which also involved getting a new motherboard and RAM. I am aware that hardware changes this large will usually make this happen, but I've tried to troubleshoot, and I've clicked the button at the bottom when you have changed your hardware, but it just tells me to try again later. Any advice?

Hi Florea,

It is possible that Windows won't be able to identify your computer correctly that is why the operating system is not activated. To address your issue, we suggest that you follow the steps in this
article on how to reactivate your Windows 10 after a hardware change.

Let us know if you need further assistance.

 

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."

 

Motherboard change unable to reactivate Windows 10 Pro -


I have searched this topic and everything seems to be almost a year old. This is a homebuilt machine circa 2015. It started with an ASUS FM2+ motherboard with an AMD A5600K processor. It was Windows 7 Pro, upgraded to Windows 8.1 Pro then to Windows 10 Pro.
Saturday the motherboard died. An exact replacement could not be located so a Gigabyte card was installed. No changes to the hard drives. Booted the machine and Windows automatically started and then did a "revert" then installed the latest updates. C Drive was in the red so I deleted all of the old install files using Windows Clean-up. Went to reactivate, checked the significant hardware change and entered my MS account information - The computer (none of my computers) were listed and now it is telling me that I have to spend $200 to buy a copy of Windows 10 Pro.
Have not yet called Customer Support as the computer is at home and I work during the day -
I do have a disk image or two that may be a year old -

Suggestions - should I just shell out the $200 and move on

TIA
