Running an old version of Windows might seem harmless—after all, “it still works.” But when Microsoft ends support for an operating system, that means no more security updates, no patches for new vulnerabilities, and no help when things go wrong. Hackers know this, and they actively target outdated systems because they’re easy to attack.
In a university environment, especially one that has access to protected health information, the risks are even higher. Unsupported systems can provide a direct entry point to sensitive data, including research files, patient information, and personal records. A single compromised computer can expose entire networks to ransomware, data theft, and operational outages. Not updating puts us in jeopardy of being out of compliance with the HIPAA security rule and increases the risk of a reportable incident.
Windows XP and 7 have been out of support for years, and Windows 10 recently reached end of regular support October 14, 2025. Devices still running these systems no longer meet WashU security requirements.
If you or your area still uses Windows 10, here is what you need to know
- WUIT will pay for an Extended Support Key until October 2026 which allows it to continue receiving required security updates.
- If your computer is managed by your department, you must obtain and install this key yourself ASAP.
- Your department is responsible for costs for this key in 10/2026 and 10/2027 with support ending 10/2028.
- Make plans to exit from Windows 10 as soon as possible prior to October 2028.
Reminder: The Extended Support Key is a temporary safety net, not a long-term solution. It’s designed to keep systems protected, and compliant with standards like HIPAA, while you plan and transition to Windows 11. Be sure to start that planning process early and before ESU support ends in 2028.
Staying current protects you, your patients, your students, and our university’s mission. Running an old OS doesn’t just put your computer at risk—it puts everyone’s data at risk.
