Support for Windows 10 will officially end on October 14, 2025, after which Microsoft will no longer provide technical assistance, feature updates, or security updates for the operating system. A lack of security updates for Windows 10 can significantly reduce system protection, increasing the risk of exploitation through new vulnerabilities and making devices more susceptible to malware, ransomware, and cyberattacks. Users are advised to either upgrade the operating system on their devices to Windows 11 if compatible, use LTSC editions, or enroll in the Windows 10 Extended Security Updates (ESU) program to continue receiving security updates and support beyond the EOL date.
