Microsoft has released Windows 11 Build 27842 to Insider program participants using the Canary channel. The update continues roll-out of the colorful battery icons in the tray, a new style of BSOD, and includes several security fixes.
Advertisеment
Changes and improvements
General
- Improved battery icons introduced in Build 26120.3000 may not be available to Windows Insiders. We've started re-rolling this change.
- Microsoft is introducing a new design for the screen that appears when the operating system crashes. The new BSOD/GSOD interface better matches the style of Windows 11 and is aimed at getting users back to work faster. The interface has been simplified, but technical information is still displayed on the screen.
This change will gradually roll out to Windows 11 Insiders on version 24H2 (and later) in the Beta, Dev, and Canary channels.
Windows Security
- Changes to the Windows Security app have begun rolling out. It will now display additional information, such as the manufacturer and version of the Pluton TPM chip, if your PC has one. You can find this information under Device security > Security processor details.
Other
- Removed support for the Visual Studio Graphics Analyzer shader debugging feature. Attempting to use this feature may crash Visual Studio or your analysis session. The company recommends using alternative tools such as PIX for D3D12 or RenderDoc.
- Microsoft has removed the bypassnro.cmd script to improve the security and usability of Windows 11. The change ensures that after the initial Windows setup phase, all users have an internet connection and a Microsoft account.
