As of October 14, Microsoft has officially ended support for Windows 10, leaving millions of users vulnerable to cybersecurity threats due to the absence of critical security updates. With nearly 200 million PCs globally running Windows 10 and many incompatible with the newer Windows 11, users face a daunting choice: upgrade for enhanced security features or risk operating unsupported systems. Microsoft offers an Extended Security Update (ESU) Program for a fee, but this is not a viable option for many. The situation underscores the urgent need for users to back up data and consider their next steps, as using an outdated operating system could lead to serious data breaches and malware attacks in a rapidly evolving cyber landscape.
