Overview
- Microsoft pushed Experimental Insider Build 26340.9212 to the Experimental Channel, which shipped on Monday, August 17, and testers began seeing per‑app toggles for camera, microphone and location for Win32 (desktop) apps.
- Independent testers reproduced the change and reported a centered system permission dialog that appears when a desktop app first requests camera or mic access, matching the smartphone‑style prompts used for Store apps.
- The rollout is inconsistent: some Insiders saw the controls automatically while others needed to enable the Win32SignatureIdentity (60730253) feature flag, showing the feature is gated and still under test.
- Microsoft did not document these per‑app controls in the build notes and recently removed another Experimental feature called the Drag Tray, underscoring that features in this channel can be altered or dropped before public release.
- Historically Win32 apps were subject to a single master toggle because they are harder to sandbox, so if shipped as tested this update would let users block specific desktop apps like browsers or game clients from using cameras, mics or location without turning access on or off for every desktop program.
