Windows 10: Struggling to Activate Win10 on new build

I have a purchased key for Win 10 Pro. I have installed win 10 pro on a new PC that I built. I have followed steps to remove my license from my old machine by typing slmgr.vbs -upk and that was successful. On my new PC whenever I use my Win10 Pro key it says it cannot activate. It provides the error 0x803fa067If I run slmgr /dlv I get this message. I've tried to contact support but the telephone number is now closed and I cannot talk to an agent for some reason... I enter my UK mobile telephone number and it just says there is an error.

I'm confused! New build, Win10 activation issue

Okay, I've been searching, but I keep finding different answers so here's my situation.

I have a laptop that came with Windows 7 loaded on it. I upgraded it to Windows 10 when that became active.

I just built myself a new desktop computer and loaded Win10 using the media creation tool and a USB drive. So Windows 10 works, but it says it's not activated and I can't do some things like change my background picture.

The new computer shows up in my account devices on the Microsoft page and the serial number says "Serial #: To be filled by O.E.M." Activation troubleshooter says, "We weren't able to activate Windows on this device" and trying to reactivate it says, "

• Device type doesn't match
• The devices listed below don’t match the type of device you’re using right now."

So, do I need to buy a copy of Win10 to be able to use all the Windows features on my new computer?

 

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
