The Task Scheduler in Windows Server 2008 R2 and later and Windows Vista and later executes tasks under a "least privileges" security context by default.

Open the properties of the task and check Run with highest privileges. Press OK, then enter the password for the administrative account when prompted. This will override the default "least privileges" behavior and will allow the task to run with administrative privileges.
