The following classification of updates are downloaded to the WolfTech WSUS server but are not approved for installation without minimal testing by IT support staff. Unless critical circumstances arise, these patches will not be approved until after each month's "Patch Tuesday" and will be accompanied by an email to the OU Admins:

WSUS Settings for Personal Computers

WSUS Clients on Personal Computers are configured with the following settings:

• Turn on Automatic Updates.
• Point to WolfTech's WSUS server.
• Set the appropriate client-side target group - ECE-Personal.
• Auto-download and install patches approved on the WSUS server at the scheduled install time.
• Set the scheduled install time to be 2:00 PM every day.
• Reschedule patch installation to the next boot time if the regular scheduled time is missed.
• Specify a 15 minute delay that Automatic Updates will wait, following system start-up, before proceeding with a scheduled installation that was missed previously. This is to ensure that the machine is fully operational before patch installation will occur.
• Allow non-admins to install patches and to delay rebooting after patch installation.
• Set the option to not restart the computer automatically during a scheduled installation if a user is logged in to the computer. Instead, Automatic Updates will notify the user to restart the computer to complete the installation.
• Enable the immediate installation of minor patches that do not require a reboot.
• Set new update detection frequency to every 8 hours.
