Hi Alan,

Thanks for sharing. I’m just starting out with this deploymenttoolkit as I was using a custom vbs wrapper.
This wrapper already had a function to log all app information to the registry so we could query this in ConfigMgr and standardise on our applications in ConfigMgr. This part was missing in the original PSADK.

Thx!
