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 determined by using the hours specified here minus zero to twenty percent of the hours specified. For example, if this policy is used to specify a 20 hour detection frequency, then all clients to which this policy is applied will check for updates anywhere between 16 and 20 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.

Note: The "Specify intranet Microsoft update service location" setting must be enabled for this policy to have effect.

Note: If the "Configure Automatic Updates" policy is disabled, this policy has no effect.
