Windows 10: After main board changes, I can't activate Win10

I have changed my mainboard, now I can't activate Win10 with my Key. I tried it by phone also, but not working.

Win10 won't activate after RAM change

Hey! I replaced my old RAM cards with two new ones, and now I'm stuck with a "activate windows" prompt in the bottom right corner of my screen. The troubleshooter does not seem to do anything (tried checking the changed hardware option + chose my device
in the list of devices + it said win10 was now activated.... but the prompt won't leave.)

I got win10 during the free upgrade period, and thus I don't have a product key... Any suggestions?

 

Activation on new board

Hi All, I have a question on activation. I have two machines, one Asrock and the other Asus. The Asrock was a free upgrade from Win 8 pro to 10 pro using my retail licence and was activated. My Asus was installed with 10 pro via a retail licence.

Now, the Asrock has been decommissioned and I'm waiting for new board to arrive (Asus)I want to use the retail 10 key for the new board but, my other Asus was activated using that key. So I went into the activation screen and changed the licence to my Win 8 Pro key and it activated with no problems.

Does that now mean that the 10 pro key is freed up to use on the new board. Or am I snookered.
Thanks in advance for any suggestions.

 

Activation options for Win10 with instant clones

We have a secure (no internet access) lab environment setup to test and validate a VMWare VDI deployment of Win10 clients.

Our issue is activation of the Win10 clients as they require re-activation every time we logoff and back on because we are using instant clones.

Does anyone have any suggestions on the best way to resolve this? Here are the options we are considering and issues as we understand them:

• Setup a KMS server
  • Requires a Volume license, which is doable
  • Documentation says we must have a minimum of 25 hosts, we don' have that in our lab
• Use our MSDN account
  • No support for Win10 KMS license
  • No support for MKS activation
• Manually activate each time
  • Gonna spend a lot of time on the phone
  • Win10 has no grace period so machines are crippled w/o activation

Anyone have a thought or suggestions? I'm hoping I missed something.

Thanks
