Microsoft has extended the Extended Security Updates (ESU) program for Windows 10 personal computers until October 12, 2027. This extension was noted in a revised support document and aims to give users more time to transition to Windows 11 while still receiving security updates. The ESU program, launched in June 2025, was initially set to conclude in October 2026. Currently, Windows 10 powers approximately 26% of desktop Windows PCs globally, with around 1 billion PCs still running it, according to Dell COO Jeffrey Clarke.
