Microsoft has extended its free consumer Windows 10 Extended Security Updates (ESU) program by an additional year, with the new deadline for critical security patches set for October 14, 2027. The ESU program was originally scheduled to end on October 12, 2026. Devices already enrolled in the program will automatically transition to the new date. Approximately 400 million active PCs are unable to upgrade to Windows 11 due to hardware limitations. IDC forecasts a 10% to 20% rise in prices for PCs, tablets, and smartphones through the end of 2026. Third-party solutions, such as unofficial Windows 10 micropatches from security firm 0patch, will be available through 2030.
