Windows 11 Build 26100.8106 (KB5079387) rolls out AI‑powered Narrator support on every device, allowing instant image descriptions that can be fed directly into Copilot with a few keystrokes. The update makes Smart App Control toggleable in Settings without requiring a clean install, while File Explorer’s file‑unblock feature has been hardened so previews of downloaded documents no longer trigger warnings or crashes.
Windows 11 Build 26100.8106 Update Brings AI‑Powered Narrator and Smart App Control – What to Know
The new Windows 11 build 26100.8106 (KB5079387) ships in both a gradual rollout for Insider Preview users and a normal rollout once it hits general availability. It’s not a security fix, but it does bring a handful of small‑but‑useful changes that can make everyday tasks feel a bit smoother.
AI‑Powered Narrator Enhancements
Narrator now works with Copilot on every Windows 11 device, not just the premium “Copilot+” PCs. Pressing the Narrator key plus Ctrl + D instantly describes whatever image is under the focus, while Ctrl + S gives a full‑screen description that appears in Copilot ready for you to tweak or ask for extra detail. The best part? The image stays on your screen until you decide to share it, so privacy stays intact. A user who often works with design mockups reported that this new workflow cut the time spent explaining screenshots by half.
Smart App Control is Now Toggleable
Smart App Control (SAC) can finally be turned on or off without a clean reinstall. Settings Windows Security App & Browser Control opens a new pane where SAC’s status is shown and the toggle is at hand. The feature, announced in a January 2026 release note, helps block untrusted or potentially harmful apps at launch. If you’re on the “clean‑install” path for SAC, this change saves you from having to wipe your PC every time you want to flip it on.
Settings Get a Fresh Look and Faster Loading
The About page under System now shows device specs in a clearer, card‑style layout that’s easy to skim. The Settings Home screen has been streamlined to match this new look, with quick links straight to Storage and other core hardware info. That extra visual cue means you no longer need to scroll through dozens of tabs just to find your CPU speed or memory size. Behind the scenes, the Settings app loads its home screen faster, so you spend less time waiting for that familiar gear icon to spin.
File Explorer Gets Practical Tweaks
Unblocking files downloaded from the internet is more reliable now, which means previewing PDFs and Office documents in File Explorer no longer triggers a pop‑up warning every single time. Voice typing (Win + H) can be used when renaming files—a small convenience that saves a keystroke for those who like to type with their hands on the keyboard. The Advanced Security Settings dialog now sorts permission entries by Principal, making it easier to see which users or groups have what rights.
Other Minor Improvements
The update nudges a few other areas into better shape: Windows Hello fingerprint recognition has been fine‑tuned for a handful of devices; safe mode now loads the taskbar reliably; and printing support extends back to older printer drivers that run on Windows 10 1607 or Server 2016. Audio handling for short MIDI messages gets a bit more robust, which can help musicians who use lightweight synthesizers.
How It Rolls Out
If you’re an Insider Preview participant, the gradual rollout means your device will receive the update in stages, so the timing may differ from a friend on another build. The normal rollout, slated for general availability, drops it to all eligible devices at once. Users should still check their Settings Update & Security Windows Update page to confirm they’re on Build 26100 or 26200 before expecting these changes.
