Description

Creates a scheduled task that will run using service-for-user (S4U).
This allows the scheduled task to run even as an unprivileged user
that is not logged into the device. This will result in lower security
context, allowing access to local resources only. The module
requires 'Logon as a batch job' permissions (SeBatchLogonRight).

This triggers on event 4101 which validates the Windows license after logon.
