        required: false
author: "Matt Davis (@mattdavispdx)"
notes:
- win_updates must be run by a user with membership in the local Administrators group
- win_updates will use the default update service configured for the machine (Windows Update, Microsoft Update, WSUS, etc)
- win_updates does not manage reboots, but will signal when a reboot is required with the reboot_required return value.
- win_updates can take a significant amount of time to complete (hours, in some cases). Performance depends on many factors, including OS version, number of updates, system load, and update server load.
