Job to update Registry Key on WES7

I wanted to update a registry key to enable TLS 1.2 on WES7 devices. I exported the registry key that I want to use to modify other devices. I placed the exported registry key on the WMS 1.4 repo under Thin Client Apps. I created an App Policy and selected the registry Key file as the application to use, the OS subtype was WES7 and I also selected the Platform Filter. I did not entered any parameters as I thought that WMS will know how to execute the file. The job was executed the Wyse device rebooted as expected to disable the write filter, it booted up and I saw the Typical message the administrator is performing changes, the job completed and the Wyse rebooted. Unfortunately, the registry key didn’t get updated. Any thoughts or suggestions.
