Your Guide to Windows 10 Update KB5055612: Features, Installation, and What Lies Ahead

The much-anticipated Windows 10 update, designated as KB5055612 (build 19045.5794), has officially begun its roll-out in the Release Preview Channel. This update serves as the inaugural preview of the May 2025 update, representing a significant maintenance update that enhances the operating system’s version 22H2 by introducing a variety of improvements and fixes.

As documented in the official changelog, users can expect notable non-security fixes as part of this build update.

Microsoft is also making strides with Windows 11, providing a preview of the next Patch Tuesday update which will introduce a plethora of new features, including Windows Recall, Click to Do, and enhancements to Semantic Indexing aimed at Copilot+ PCs.

This release will also implement enhancements across several key components, including Widgets, File Explorer, Settings, Windows Share, Start Menu, Taskbar, and beyond.

Understanding Windows 10 End of Support

Important news for all Windows 10 users: Microsoft has officially announced that support for Windows 10 will conclude on October 14, 2025. Although maintenance updates are still being released before this date, after October 2025, you will no longer receive security updates, bug fixes, new features, or any technical support. This shift will leave your system potentially susceptible to security vulnerabilities and performance declines.

Additionally, Microsoft has confirmed the retirement of support for Microsoft 365 apps on Windows 10. Although applications like Word, Excel, and PowerPoint will still function, they won’t receive updates, leading to reduced reliability over time.

For those committed to continuing with Windows 10, Microsoft has introduced Extended Security Updates (ESU) for consumers—a service that was initially limited to organizations requiring legacy system support. This means you can keep your system secure longer, though transitioning to Windows 11 or alternative operating systems like Linux Mint is advisable for long-term efficacy.
