Microsoft will provide security updates for Windows 10 users until October 10, 2028, despite the end of official support on October 14, 2025. Microsoft 365 subscribers on Windows 10 will continue to receive security patches for applications like Word and Excel, but support will be limited to troubleshooting for those unable to upgrade to Windows 11. If issues arise that are exclusive to Microsoft 365 apps on Windows 10 and do not occur on Windows 11, users will be encouraged to upgrade. Transitioning to Windows 11 has faced resistance due to hardware requirements, particularly affecting users of older Surface devices. As of now, Windows 10 holds a 53 percent global desktop market share, while Windows 11 has 44 percent.
