User Story

As we feel its a basic thing, and really nice to know information for server administrators if thir server is waiting for a reboot after a Windows Update or Software been installed. Even though this should be done automaticly , its not alwayes working as intended.

Details of User Story

We been using this PS script from Microsoft , but as we bought PTRG we would have hoped for a sensor that could do the same:

Acceptance criteria

• Registery Check is the most used so if this could be working it would solve most cases.
