# Windows 10 ESU

The **Extended Security Updates (ESU)** program is a paid service provided by Microsoft that allows devices running Windows 10 to continue receiving critical security updates for up to three years after the official end-of-support date (October 14, 2025).

## Technical Requirements for Activation
To participate in the ESU program at the Universität Greifswald, the following conditions must be met:
- **Version**: The system must be running Windows 10 version 22H2.
- **Patch Level**: Update **KB5046613** or a newer version must be installed (generally true if updates were successfully installed since December 2024).
- **Permissions**: The user must have local administrator rights on the device.
- **Connectivity**: Activation requires a **wired connection** to the university network (IP range `141.53.*.*`). Activation is **not possible** via:
    - VPN
    - WLAN
    - Guest networks

## Procurement and Implementation
Licenses for the ESU program are handled by the [[referat-beschaffung]]. Once procured, users are provided with a link to a download for an activation assistant provided by the URZ.
