Windows 10: Windows 10 Pro Reactivation on Daily Basis

I have a problem with my PC requiring reactivation on a daily basis. The activation error is 0xC004F050 which suggests that I have changed the motherboard but that is not the case. I can reactivate the Windows 10 Pro account with the Troubleshooter or by re-entering the Product Key or by using the online activation, etc., but the activation error returns the next day. I purchased an OEM version of Windows 10 Pro 64 last May 2018 for a new home built PC and it worked fine until about a month ago. I updated the motherboard BIOS and some drivers and the Intel Management Engine but have not changed any hardware except for swapping monitors. I prefer not to reinstall Windows if I don't have to.


What can I do to fix this daily reactivation routine?

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

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
