I am fine-tuning Administrative Services and have a question re Automatic Update in Services, which is now on Automatic. I have automatic updates disabled and do all Microsoft updates manually.

Microsoft Service Description: Enables the download and installation of Windows updates. If this service is disabled, this computer will not be able to use the Automatic Updates feature or the Windows Update Web site.
