Windows 10: activation needs reactivation frequently

I have activated my W10, but frequently I get a message saying I need to activate. If I run troubleshooting, it will activate. why doesn't the activation stay on?

Reactivation Failed

I have just recently replaced my motherboard/processor and I reformatted my windows hard drive. I gone through the hardware changes steps, I chose the old machine listed on my account and clicked on ACTIVATE.

It now tells me that:

"Unable to activate Windows

We can't reactivate Windows on this device. Try again later."

What am I missing here?

 

Need Serious Help: How To Record Video of What is Done on my PC?

I suggest the following simple steps:

1. Set the autosave options in MS Office to a low value say 5 minutes.
2. Setup file history to autosave frequently - the shortest period is 5 mins
3. Install Macrium Reflect Free and configure it to do a daily incremental system backup

You should be well covered if you do the above to protect your key files.

 

Issue Activating Windows After Changing Motherboard and CPU

Thanks for the links, but I've already done the steps in both of those, as listed in my initial post. The name of my computer isn't listed in the troubleshooting / reactivation window even though Windows was activated on that computer previously.
