Microsoft has released Windows 11 Insider Release Preview Build 28000.2173 for users testing the upcoming Windows 11 version 26H1 update. The new build, released under KB5089570, introduces several improvements focused on gaming, File Explorer, performance, and system reliability.
The update is now rolling out to Windows Insiders in the Release Preview channel and gives an early look at some of the features Microsoft is preparing for future Windows 11 devices.
Windows 11 Build 28000.2173 Brings New Features to 26H1
According to Microsoft’s release notes and early reports, Build 28000.2173 focuses heavily on refining the Windows 11 experience rather than introducing a complete redesign.
Some of the biggest highlights include:
- Xbox Mode improvements for gaming-focused PCs
- File Explorer enhancements
- Input and accessibility refinements
- Enterprise and driver policy changes
- Performance and reliability fixes
The update is part of Microsoft’s ongoing work on Windows 11 version 26H1, which is currently expected to target newer hardware platforms and future AI-powered PCs.
Xbox Mode Could Improve Gaming on Windows PCs
One of the most interesting additions mentioned in reports is Xbox Mode support. While Microsoft has not fully detailed all functionality yet, the feature appears aimed at improving the gaming experience on Windows devices.
The addition further strengthens Microsoft’s push toward tighter integration between Xbox and Windows ecosystems.
Gaming-focused improvements in recent Insider builds suggest Microsoft is continuing to optimize Windows 11 for handheld gaming PCs, gaming laptops, and next-generation hardware.
File Explorer Continues to Receive Upgrades
Microsoft is also making more changes to File Explorer in Build 28000.2173.
File Explorer has become one of the most actively updated parts of Windows 11 over the past year, with Microsoft steadily improving performance, usability, and modern UI consistency.
The latest Release Preview build reportedly includes:
- Stability improvements
- Better responsiveness
- Refinements to navigation and usability
- Additional bug fixes
Microsoft has been gradually modernizing File Explorer while also addressing complaints from users regarding slow loading times and inconsistent behavior.
Windows 11 26H1 Appears Focused on Future Hardware
Reports indicate that Windows 11 version 26H1 may primarily target new hardware platforms, especially future Copilot+ PCs powered by next-generation chips.
Microsoft previously suggested that 26H1 is not intended to be the standard upgrade path for all existing Windows 11 devices. Instead, it appears designed for specific hardware and silicon platforms.
This could mean:
- Exclusive AI-focused features
- Better optimization for NPUs
- Enhanced gaming capabilities
- Improved power efficiency
- Advanced hardware integration
The strategy aligns with Microsoft’s broader push toward AI-powered Windows experiences.
Microsoft Is Restructuring the Windows Insider Program
The release of Build 28000.2173 also comes during a major restructuring of the Windows Insider Program.
Microsoft recently simplified Insider channels and introduced new ways for users to access experimental features directly through Settings without relying on third-party tools.
The company is increasingly separating:
- Stable preview builds
- Experimental features
- Future hardware platform testing
This allows Microsoft to test major platform changes more efficiently while reducing confusion among Insider users.
More AI and Performance Features Expected Soon
While Build 28000.2173 mainly focuses on refinements, Microsoft is clearly laying the groundwork for larger Windows 11 upgrades tied to AI hardware and next-generation PCs.
Recent Insider builds have already introduced features such as:
- NPU monitoring in Task Manager
- Shared audio improvements
- Multi-app camera support
- Accessibility upgrades
- Better touchpad customization
These additions suggest Microsoft is steadily preparing Windows 11 for more advanced AI-assisted workflows and productivity tools.
Final Thoughts
Windows 11 Insider Release Preview Build 28000.2173 may not be a massive feature drop, but it offers important clues about Microsoft’s direction for Windows 11 version 26H1.
With Xbox Mode improvements, File Explorer refinements, and continued optimization for future AI-powered hardware, Microsoft appears focused on making Windows 11 smarter, faster, and more gaming-friendly.
As development continues, more features are expected to appear in upcoming Insider builds before a wider rollout later in the future.
