I know this is a bit more substantial than a RCT, but a wizard to help with Windows Servicing would be great.
I'd see this feature helping to create:
Custom Action Scripts
- To apply customizations, disable services, etc
The Wizard would allow us to create "Servicing Templates" which would be stored on the RMS Server, similar to Kiosk Profiles.
A Servicing Template would then be applied to a Collection or Machine, and it would copy down all of the files onto the machines into the correct locations so they are staged when the Feature Update Applies
Basically, an "Easy Button" to customize Servicing, similar to the "Easy Button" you have for Kiosks.
