Windows 11 Canary Build 29558 Brings Many Command Line Improvements, KB5079490 Enhances Insider Experience

In addition to two new Windows 11 builds for Dev and Beta Insiders that upgrades Task Manager and enables Administrator Protection toggle, Microsoft has released a few for Canary testers. The Preview Build 29558.1000 is now available to Canary Channel Insiders on the optional 29500 build series.

Meanwhile, another Insider Build 28020.1797 (under KB5079490) lands for other Canary testers out there. Well, this one doesn’t come with much of the changes, as Microsoft only notes that this update “includes a small set of general improvements and fixes that improve the overall experience for Insiders.”

Canary Preview Build 29558.1000 comes with plenty of Command Line improvements

Microsoft says that most of the updates outlined below have come from Windows Insiders and community contributors. 

• Optional new Atlas/Direct3D rendering path (UseDx): available behind a registry key (HKCU\Console, DWORD UseDx=1).
• Regular Expression search: the Find dialog now supports regular expressions. 
• Bold font rendering: the original rendering engine now supports bold fonts.
• Paste reliability improvement: resolves a longstanding issue where some pasted characters could be dropped when the output code page couldn’t represent them.
• Accessibility improvements: rewritten legacy MSAA integration and parts of UI Automation support.
• Snap-on-input behavior: now only enabled by default when VT processing is enabled. More reliable snap on input/output in WSL and PowerShell. 
• Clipboard enhancements: supports OSC 52 (Manipulate Selection Data) for writing selection data to the clipboard. 
• Graphical content: adds support for Sixel-based images. Alt + Numpad + clipboard text fix: avoids mistranslating Codepage 936 text when generating Alt + Numpad events for clipboard content. 
• Performance: scrolling text performance improvements (up to ~10x in some scenarios). 
• Rectangular selection: fixes rectangular copy via Edit > Mark.

Microsoft futher says that the Windows Console can now display inline images, allowing tools like WinGet, for example, to display application icons. In addition, the company has also changed how the pop-up dialogs look inside the console to improve their compatibility with screen readers, assistive technologies, and other terminal emulators. This includes the F7 history window as well as the F2 and F4 line editing windows.

Last but not least, this Canary build also updates chkdsk, which now support specifying volumes with spaces if you have the path encased in quotes (for example, chkdsk “C:\My Volume\SD Card”). Moreover, Microsoft has also removed an “unexpected error message when opening Group Policy Editor in the previous two flights.”
