Windows 11 Insider Experimental Preview Build 26300.8935: File Explorer Gets Faster and More Responsive

Microsoft has released Windows 11 Insider Experimental Preview Build 26300.8935, introducing a handful of performance-focused improvements aimed at making File Explorer faster and more responsive. While this build doesn’t include major new features, it delivers meaningful quality-of-life enhancements that users will notice during everyday file management.

The latest experimental update focuses on improving file deletion performance, reducing File Explorer launch times, and enhancing touch interactions on the Home page.

What’s New in Windows 11 Insider Experimental Preview Build 26300.8935?

Faster File Deletion

Microsoft has optimized File Explorer to make deleting large, fragmented files significantly faster in specific scenarios.

Users who frequently work with large media files, backups, virtual machines, or development projects should experience quicker deletion operations with less waiting.

Faster File Explorer Home

The File Explorer Home page now launches faster, improving the overall responsiveness of one of Windows 11’s most frequently used apps.

This optimization reduces loading time and helps users access recent files and folders more quickly after opening File Explorer.

Touch Scrolling for Recommended Files

Microsoft has also improved the Recommended section on the File Explorer Home page.

The file carousel now supports touch scrolling, making it much easier for users on touchscreen devices, tablets, and 2-in-1 Windows PCs to browse recommended files with natural swipe gestures.

Complete List of Improvements

• Faster deletion of large, fragmented files in supported scenarios.
• Improved File Explorer Home startup performance.
• Touch scrolling support added to the Recommended files carousel on Home.

A Small Update with Practical Benefits

Although Build 26300.8935 doesn’t introduce headline-grabbing features, it continues Microsoft’s ongoing effort to refine Windows 11 through performance optimizations and usability improvements.

File Explorer is one of the most heavily used components of Windows, and improvements to responsiveness, file operations, and touch support can have a noticeable impact on daily productivity.

As Microsoft continues testing experimental builds, more refinements and features are expected before they make their way into future Windows 11 Insider channels and eventually the stable release.

Final Thoughts

Windows 11 Insider Experimental Preview Build 26300.8935 focuses on polishing the File Explorer experience rather than adding new capabilities. Faster file deletion, improved Home launch performance, and better touch navigation make the update a worthwhile improvement for Insider users, especially those using large files or touchscreen devices.

If testing goes well, these enhancements are likely to be included in upcoming Windows 11 preview builds before rolling out more broadly.
