Download Windows 10 KB5063709 for Extended Update Support

As part of the August 2025 Patch Tuesday, Microsoft has released Windows 10 KB5063709. While this update does not introduce new features, it plays a vital role in preparing users for the impending end of support on October 14, 2025. Users seeking to extend their support options can do so by either linking a Microsoft account (with settings syncing) or paying a fee of $30 for continued updates—providing a glimpse into the Extended Security Updates (ESU) option in Windows 10.

Delivered as a mandatory security update, Windows 10 KB5063709 downloads automatically. Interestingly, upon checking my Windows Update, I observed that the installation was already in progress without manually checking. The size of this update is approximately 200MB through Windows Update; however, if you prefer using the Update Catalog, the file size will be close to 700MB.

This cumulative update appears as “2025-08 Cumulative Update for Windows 10 Version 22H2 for x64-based Systems (KB5063709)”. Following the installation, users will see their system upgraded to Windows 10 Build 19045.6216. For those still on Windows 10 Version 21H2 (which is not recommended), the update will bring the system to Build 19041.6216, with no significant visual changes.

Additionally, Microsoft has extended updates for Windows 11, specifically for version 24H2, releasing KB5063878.

Post-update, many users are now able to access the enrollment wizard for the Extended Security Updates (ESU).A new “Enroll Now”link has surfaced within the Windows Update settings, marking a significant step toward enhancing security for eligible devices.

Initially, this enrollment link began rolling out in July 2025; however, users encountered issues, including unexpected crashes that prevented successful enrollment. Observations from Windows Latest confirmed that all activated Windows 10 licenses qualify for ESU, regardless of Microsoft account status.

Enroll in Extended Security Updates to stay protected

The cause of enrollment failures was traced back to incomplete registrations on Microsoft’s end. Affected users could see the enrollment toggle but faced limitations in selecting available options, rendering the ESU wizard unusable. Fortunately, these issues have been resolved with the release of KB5063709.

The update also expands the availability of the ESU tool to more computers, so users previously unable to locate the extension option should revisit the Windows Update page following this update.

When you click on “Enroll Now, ”a new window will provide details about the support timeline for Windows 10, indicating the conclusion of its support in October 2025. Interestingly, Microsoft does not feature references to Windows 11 in this dialog, granting users an opportunity to extend their updates while they consider their next steps in PC upgrades.

Upon enrollment, users have several options:

The preferred option involves linking a Microsoft account, which requires syncing settings to OneDrive. This is aimed at easing future transitions, especially as Windows 10 approaches its end of life.
If you prefer to retain your local account, you can utilize Microsoft Rewards points (1, 000) to enroll, a choice that cannot be reversed.
Lastly, you can also extend support for $30 without linking a Microsoft account, although you will still need to create one to complete the transaction.
