When an operating system reaches end of life, the vendor stops issuing security patches, bug fixes, and technical support. That means new vulnerabilities discovered after today won’t be fixed, leaving your system increasingly exposed.
We have been advising people who use UTHSC Windows 10 machines that they need to upgrade. If your personal device was purchased before 2018, the hardware in that device cannot handle the software update to Windows 11. We highly recommend updating your devices to a supported operating system.
Once security updates stop, any zero-day vulnerability or exploit could leave your device and data at serious risk.
