Windows 11 build 27842 introduces updated green screen of death and improved battery indicator

New Windows 11 Build 27842 Rollout for Insiders in the Canary Channel

Exciting updates have emerged for Windows Insiders in the Canary Channel with the release of build 27842. This latest build brings a host of enhancements, including a reimagined blue screen of death (SAD face no more), an updated battery indicator, and comprehensive details about Pluton TPM chips within the Windows Security application. Additionally, users should note the removal of the bypassnro command, although a workaround is available.

Highlights of the Build

[General Enhancements]

An improved battery icon is being reintroduced to Windows 11, though it may temporarily vanish for some Insiders during this flight rollout.

A newly streamlined interface for unexpected restarts has been unveiled. This update is designed to align more closely with Windows 11’s aesthetic while facilitating quicker user re-engagement with their tasks. Currently labeled as a “green screen” for Windows Insiders, this feature will be made available on Windows 11 version 24H2 and newer in the Beta, Dev, and Canary Channels.

[Windows Security Updates]

The Windows Security app will now provide additional details about the manufacturer and version of Pluton TPM chips located under Device Security > Security Processor Details for eligible devices.

[Other Notable Changes]

The Shader Debugging feature in the Visual Studio Graphics Analyzer is being deprecated. Users are advised to switch to alternate graphics debuggers like PIX for D3D12 or RenderDoc as using the deprecated feature may lead to crashes.

To enhance the overall security of Windows 11, the bypassnro.cmd script is removed, ensuring users complete the setup process with active internet connectivity and a Microsoft Account.
