Windows 10 will reach its end of life on October 13, 2026. Microsoft is encouraging users to enroll in the Extended Security Updates (ESU) program before this date to avoid increased vulnerability to viruses and malware. Windows 10's market share has increased from 42% to 46%, while Windows 11 remains below 50%. The first Windows 10 ESU update for 2026, KB5073724, has been released, addressing 112 security issues, including 57 Elevation of Privilege vulnerabilities, 22 Information Disclosure vulnerabilities, and 5 Spoofing vulnerabilities. The January 2026 update will introduce new Secure Boot certificates to mitigate security risks. Payment options for the ESU include cash, Reward points, or a complimentary option for Microsoft account holders syncing settings via OneDrive.
