# WSUS

**WSUS** (Windows Server Update Services) is a centralized system managed by the [[universitatsrechenzentrum-urz]] used to provide a centralized update service and distribute patches and updates for Microsoft Windows operating systems and other Microsoft software across the university network.

It allows the URZ to manage the distribution of Microsoft updates to client machines, reducing the need for every individual device to download updates directly from external Microsoft servers.

## Access and Configuration
Access to WSUS is restricted to computers that are members of the Windows domain. These devices are automatically configured by the domain to receive updates from the internal WSUS server.

## Usage Requirements
- **Mandatory**: Usage is compulsory for all devices enrolled in [[windows-vollservice]].
- **Optional**: For other domain-joined devices, users may bypass the internal WSUS server and check for updates directly from Microsoft via the Windows Update settings ("Suchen Sie online nach Updates von Microsoft Update").
