Microsoft Releases Update KB5063842 for Windows 10 Users

27 Aug 2025

As the world anticipates the end of mainstream support for Windows 10, Microsoft has rolled out one of its final updates, KB5063842. Unlike previous updates, this release does not bring profound system alterations, but instead offers minor bug fixes and a few notable new features aimed at enhancing user experience and preparatory transitions.

New Features in KB5063842

KB5063842 introduces two main innovations designed for increased functionality and security. Firstly, a new feature will allow users to block outbound network traffic. This addition is particularly beneficial for businesses looking to secure their networks against unauthorized data outflows. However, there is a caveat; users must be in possession of a keyless Extended Security Updates (ESU) solution and be subscribed to Windows 365. This combination underscores Microsoft’s strategy to refine its services for an enterprise audience and ensure continued security support for its robust operating system.

The second feature of note is the Windows Backup for Organizations now becoming generally available. This feature is tailored towards facilitating the seamless transition from Windows 10 to Windows 11 devices. By enhancing backup and restore capabilities, organizations can ensure business continuity during this transition, mitigating the risks associated with data loss.

Transition to Windows 11

With the end of support for Windows 10 scheduled for October 14, a pivotal shift is underway as businesses and individual users prepare to transition to Windows 11. Despite more than half of devices globally now running Windows 11, a substantial 40% still operate on Windows 10. This hesitance primarily stems from the lack of hardware support necessary to enable Windows 11’s enhanced security features on existing PCs.

Historically, Windows 10 mirrors the evergreen status of its predecessor, Windows 7, which retained popularity long after subsequent versions were released. As seen with the long-lasting use of Windows XP, familiarity and reliability often delay users’ migration to new systems.

Microsoft’s preceding Mojave Experiment, a marketing initiative that rebranded Windows Vista to highlight its unseen features, could potentially be revisited to persuade users towards Windows 11. Yet the looming end of security updates is, in itself, a powerful motivator for change.

As Windows 10 approaches its twilight, KB5063842 serves as a reminder of Microsoft’s commitment to maintain system integrity and support while urging the transition to future-ready solutions.
