Official mainstream support for Windows 10 is set to conclude on October 14, 2025. After this date, users without the Extended Security Updates (ESU) program will no longer receive security updates. However, those who enroll in the ESU program can continue to benefit from critical security updates until October 13, 2026.
Enhancements with KB5063709
The recent KB5063709 update introduces a new feature within the “Windows Update” section of system settings—a button labeled “Enroll now.” This functionality allows users to seamlessly register for the ESU program, thereby activating extended support.
Prior to this update, some users encountered issues where the ESU logon wizard would crash. The KB5063709 update addresses this problem, ensuring a smoother registration process. Beyond this crucial fix, the update also brings a host of other enhancements:
- Core File System Optimizations: These improvements aim to bolster system stability during operation.
- Input Method Adjustments: Enhancements have been made to the emoji panel, phonetic input, and Changjie input methods.
- Secure Boot Improvements: Modifications have been implemented to safeguard the integrity of the boot process.
- Mobile Profile Settings: Updates relevant to devices with corresponding modules have also been included.
From a technical standpoint, KB5063709 upgrades Windows 10, version 22H2, to build number 19045.6216 and Windows 10, version 21H2, to build number 19044.6216. This ensures that all systems wishing to participate in the ESU program are equipped with the necessary technical foundation.
There are multiple avenues for users to register for the ESU program. Free registration is available for those utilizing a Microsoft account with synchronized settings. Alternatively, users can redeem Microsoft Rewards points or pay a one-time fee to enroll. It is important to note that users who previously relied solely on a local account must create a Microsoft account to take part in the ESU.
