Excerpt: Microsoft has released Windows 11 Release Preview Builds 26100.9539 and 26200.9539 with improvements to File Explorer, Emoji 17.0, Windows Recovery, accessibility and everyday productivity.
What Happened? Microsoft released Windows 11 Release Preview Builds 26100.9539 and 26200.9539 on September 10, 2026, for Windows 11 versions 24H2 and 25H2. The update is being delivered through the Windows Insider Release Preview Channel, so availability can vary during the rollout.
What Has Changed? File Explorer receives several improvements. Non-HTML files such as PDFs can now be previewed automatically, while HTML files downloaded from the web display a Preview anyway option. File Explorer Home also remembers whether sections were expanded or collapsed.
Windows now supports Emoji 17.0, including new emoji. Users can open the emoji panel with:
Windows + . (Period)
There are also accessibility improvements. A new Open apps maximized option can automatically open applications in a maximized state, which may help users who prefer a consistent full-screen workspace.
The update also improves the Magnifier experience and adds additional precision-touchpad gestures.
An Important Recovery Improvement Windows Recovery Environment, or WinRE, can now automatically reuse eligible Wi-Fi profiles already saved in Windows during supported recovery situations. This can help a device get online during certain recovery workflows without requiring Wi-Fi credentials to be entered again.
Who Should Care? These improvements are useful for students, teachers, office professionals and IT users. Better File Explorer previews can speed up file management, while accessibility and recovery improvements can make Windows easier to use and troubleshoot.
Because this is a Release Preview build, users should remember that features can continue changing before broader availability.
