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

 

Win10: windows update stuck at never ending loop ?

When in win10:

• Update&security -> Windows update -> Finding update... .... .... ....

Planning to download the latest Win10.ISO (vers.1803) and manually update:
- Then wait that my ordered new SSD arrives and clone the old HDD to it.

 

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?
