Microsoft has released Windows 11 Insider Preview Build 27686 to Windows Insiders in the Canary Channel.

Announcing Windows 11 Insider Preview Build 27686 (Canary Channel)

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 27686 to the Canary Channel.

What’s new with Build 27686

Windows Sandbox Client Preview

This build includes the new Windows Sandbox Client Preview that is now updated via the Microsoft Store. As part of this preview, we’re introducing runtime clipboard redirection, audio/video input control, and the ability to share folders with the host at runtime. You can access these via the new “…” icon at the upper right on the app.  Additionally, this preview includes a super early version of command line support (commands may change over time). You can use ‘wsb.exe –help’ command for more information.

FEEDBACK: Send us feedback in Feedback Hub (WIN + F) under Security & Privacy > Windows Sandbox.

Changes and Improvements

[General]

• Some features that were previously rolled out to Insiders in the Canary Channel may disappear as we flight newer 27xxx series builds. These features should begin rolling out again to Insiders over time.
• We’ve made optimizations to improve battery life for PCs running Build 27686+ in the Canary Channel. Let us know what you think and if you are not seeing the battery life on your PC you are expecting, let us know via Feedback Hub. When filing feedback in Feedback Hub on any battery life issues you experience, be sure to use the “Start recording” button to capture additional logs.

[Settings]

• In response to feedback, we have added a detach virtual hard disk (VHD/`VHDx) button to Settings making it much simpler to detach your VHD/VHDx as needed. This option is available under Settings > System > Storage > Disks & Volumes, in the properties for your VHD/VHDx.

[Networking]

• To help us evaluate future improvements in network performance, your device may periodically run network tests in the background to collect diagnostic data. These tests will use a small amount of data (up to 10MB/day) and will only run on Ethernet and Wi-Fi connections that are not marked as metered. This will only occur on PCs in the Canary Channel running Build 27686 and higher.

[Storage]

• When formatting disks from the command line using the  format command, we’ve increased the FAT32 size limit from 32GB to 2TB.

Fixes

[Dev Drive]

• Fixed an issue where  Dev Drive VHDs weren’t automatically re-mounting when the underlying volume was dismounted and brought back online.

[Lock screen]

• Did some work to help address an issue where the battery icon displayed on the lock screen might be out of sync with the actual battery level of your PC.

[Windows Security]

• Fixed an issue in the Windows Security app where if you browsed the networks under Firewall & Network protection, it showed a broken glyph (a rectangle) next to the network name rather than a network icon.

[Settings]

• Fixed an issue under Settings > System > Storage > Disks and Volumes, where there was no space between the Create and Attach VHD buttons.
• Fixed an issue where the power mode option in Settings > System > Power & Battery was showing in cases where it couldn’t be changed, leading to a blank dropdown.
• Fixed an issue where if you searched in Settings for Kiosk and clicked the result for setting up  kiosk mode, it wouldn’t navigate to the correct page for doing that.

[Other]

• Fixed an issue in Registry Editor where when editing a DWORD or QWORD if you pasted in a HEX value into the text box and saved it, the value saved might not be the one you had entered (for example, pasting 0x1 would become 0x411).
