Automatic Updates detection frequency

Specifies the hours that Windows will use to determine how long to wait before checking for available updates. The exact wait time is a sum of the specific value and a random variant of 0-4 hours. If the status is set to Enabled, Windows will check for available updates at the specified interval. If the status is set to Disabled or Not Configured, Windows will check for available updates at the default interval of 22 hours.
