Windows Software Update Service (WSUS)

Windows Software Update Service (WSUS)

Promoting security while maintaining a superior technological environment, Penn State supports an automatic update service for Microsoft Windows operating systems upgrades. As Windows releases critical updates for individual computers, University affiliates have the ability to install necessary upgrades through the Penn State network – as opposed to going through an outside network. The opt-in service is used to obtain critical security updates, service packs, and the latest Microsoft product upgrades.

Windows machines attached as members to the Penn State Active Directory services domain, or WINAD, are already configured to receive updates from the Penn State WSUS server.

University affiliates not attached as members of the WINAD service can configure machines to receive updates from Penn State’s WSUS server.

Users leaving the University need to ensure that individual machine settings revert to receiving updates from Microsoft.


Clients can be configured to use certain servers to check for updates. The Penn State WSUS server is Four updates are made daily to the server with the latest updates and patches from Microsoft.

Once configured, the WSUS client will query the WSUS server approximately every six hours.

The WSUS client allows users to choose from three configuration options while utilizing idle network bandwidth.

New update notifications can be received without downloading the updates.

NOTE: If notification or auto-download with notification has been selected, approval is required prior to the updates being installed. Only administrative users may approve the update.

The WSUS client logs all activities to a log file labeled Windows Update.log. Typically, the file is located in C:\Windows or C:\WINNT.
