The ZID has already communicated the upcoming end of support via various channels, including the ZID web page and the Connect IT events for IT representatives. Most of the centrally managed PCs have already been upgraded to Windows 11. Standard administration, lecture hall and computer room PCs were replaced in the summer of last year. These PCs are generally replaced every 5–6 years to meet the current requirements of the university.
The extended security updates (Extended Security Updates, ESU) offered by Microsoft are reserved exclusively for private users and are not available for devices running Windows 10 Enterprise versions at the University of Vienna.
Why continuing to operate without updates is risky
Operating systems are subject to a technological life cycle. Over time, older versions no longer meet the requirements for IT security, hardware compatibility and software functionality. Windows 10 was released in 2015 and is now being replaced by Windows 11.
With the end of regular support on 14.10.2025,
- no automatic security updates will be provided,
- new critical vulnerabilities will remain open, and
- technical support from Microsoft will no longer be available.
This means that secure use of Windows 10 is no longer guaranteed. The risk of malware and ransomware attacks increases. Devices running Windows 10 can be misused as a gateway into the university data network.
Which version of Windows am I using?
If you are unsure which version of Windows is installed on your device, you can find a user guide on the Microsoft website on how to retrieve system information of your Windows device.
Switchover for centrally managed PCs
From 01.12.2025, Windows 10 can no longer be used on centrally managed PCs to protect the IT infrastructure of the University of Vienna.
- It will then no longer be possible to log in to these devices (desktop and notebook PCs).
- Windows 10 can no longer be reinstalled once support ends on 14.10.2025.
What you should do now:
- Users with Windows 10 should contact your IT representative to plan the switch to Windows 11.
- Save your locally stored data in advance to an external medium, such as the Z: drive, Share, u:cloud or a USB flash drive.
Switchover for locally managed devices
Users of locally managed devices must take action themselves:
- If you have a valid Windows 10 license, the upgrade to Windows 11 is usually free of charge – provided that your hardware is compatible.
- Check your system compatibility with the free app PC Health Check.
- Older hardware may not meet the requirements of Windows 11.
For technical, organisational and IT security reasons, the ZID will not procure, distribute or support Extended Security Updates. This means that no extended security updates provided by the ZID are available to members of the University of Vienna. The continued operation of devices running Windows 10 without security updates is at the own risk of the respective organisational units and users.
What happens if I do nothing?
Technically, Windows 10 will continue to function without security updates after 14.10.2025. However:
- Security gaps will remain open and new threats will no longer be defended against.
- Hackers can specifically use vulnerabilities.
- Sensitive activities, such as the processing of personal data, are no longer recommended.
- Compatibility problems with new hardware and software will increase.
- Even a virus scanner does not offer complete protection, as it relies on current updates.
Where can I get help?
If you have questions or need support with switching to Windows 11, please contact your IT representative.
