Title

The update check interval must be configured and set to 30 days. (Cat II impact)

Discussion

Although Microsoft thoroughly tests all patches and service packs before they are published, organizations should carefully control all of the software that is installed on their managed computers. This setting specifies the update check interval, automatic installation, and the default interval value, which is 30 days. If you enable this policy setting, the user will not be able to configure the update check interval, and computers will not automatically download and install updates for Internet Explorer. The update check interval must be specified. If you disable or do not configure this policy setting, the user will have the freedom to configure the update check interval.
