Win PE not working after an ADK update

Config Manager CB 2303

Yesterday I applied the latest ADK and all seemed to go OK but now I cant use WinPE to image any devices.

The devices will boot into Win PE but will not get as far as the next step where we choose which task sequence to run. The device will just reboot. I have tried different models, all fail.

I have rebooted the server (several times)

I have re-installed the ADK and the WIN PE add-on and re-distributed to the DP.

Every time I update the DP (we only have one) I get this error below.

Note the second image.

Can anyone tell me what the problem is?

We are gradually moving away from MECM imaging but still need it pretty much daily.

Thank you

Adam.
