Companies both large and small share this one cybersecurity problem. They have computers that are still running older operating systems. Staff might use these devices only occasionally. Or the company may be running customized software that won’t run on newer OS versions.
The problem is that when the OS becomes outdated, the system is open to cyberattacks. When Microsoft or another developer retires an OS, it means that it is no longer supported. No more feature updates and no more security patches for newly found vulnerabilities.
The latest operating system to lose all support is Windows 8.1. Microsoft released the OS in 2013, and it was officially retired on January 10, 2023.
