Problem

You install latest Windows Assessment and Deployment Kit (Windows ADK) on the server where KSC is installed, but KSC console still shows message "to deploy OS images, you must install the Windows Assessment and Deployment Kit (Windows ADK) on the device that has KSC installed".

Solution

KSC doesn't see all the needed WADK components being installed. Because Microsoft is always changing components within their installation packages, we recommend to install all utilities from the Microsoft's official article.

1.  Go to https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install

2.  Download all utilities under "The Windows ADK includes:" including WinPE and WSIM.
