Announcing Windows 11 Insider Preview Build 25169

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 25169 to the Dev Channel.

TL;DR

What’s new

Multi-App Kiosk Mode

Multi-app kiosk mode is a lockdown feature for Windows 11 that allows an IT administrator to select a set of allowable apps to run on the device, while all other functionalities are blocked. This enables you to create multiple different apps and access configurations for different user types, all on a single device.

Some lockdown customizations include:

Multi-app kiosk mode is ideal for scenarios in which multiple people need to use the same device. This can include frontline workers and retail scenarios, education and test taking.

Currently, multi-app kiosk mode can be enabled using PowerShell and WMI Bridge, with support for Intune/MDM and provisioning package configuration coming soon.

To configure using WMI, follow these instructions. Using the Windows 10 sample XML will enable the feature, but will result in an empty Start menu. To populate the Start menu with your apps, follow these instructions to generate the list of pinned apps, then add it to your XML file after closing the StartLayout section, like the below:

About the Dev Channel

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

These aren’t always stable builds, and sometimes you will see issues that block key activities or require workarounds. It is important to make sure you read the known issues listed in our blog posts as we document many of these issues with each flight.

Build numbers are higher in the Dev Channel than the Windows 11 preview builds in the Beta and Release Preview Channels. You will not be able to switch from the Dev Channel to the Beta or Release Preview Channels without doing a clean install back to the released version of Windows 11 currently.

ALSO: Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
