[1809, ou] Windows 10 Activation by MAK not sticking

[moserbr]

I have a fleet of a couple dozen laptops that I am rolling out next week.

 

They are getting imaged from an 1809 Windows Education image.

 

I got my MAK activation product key from VLSC, like usual, used CMD slmgr.exe /upk, then /ipk xxxxxxxx, then /ato.

 

The activation works, it seems, until after a restart when the Activation page in settings shows "Windows is not Activated"

 

Troubleshooting gives the following code 0x80070520

 

The activation gives 0xC004F050

 

This really isn't any different than how I've normally activated, but it just doesn't seem to be sticking.... any ideas? Please ask me to clarify if I haven't supplied enough info.
