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.
