Microsoft has introduced Coreutils, a new feature for Windows 11, that enables developers to run a variety of popular Linux command-line utilities natively, eliminating the need for emulators or virtual machines like Windows Subsystem for Linux (WSL). This feature was unveiled at the Build 2026 developer conference in Seattle, aiming to minimize the "cognitive load" that developers experience while switching between different platforms.
Traditionally, accessing essential Linux command-line utilities on Windows required workarounds, such as using Git Bash or WSL, which could be time-consuming and inefficient. With Coreutils, developers can now execute many Linux commands directly from the Windows CMD, PowerShell, or Windows Terminal, streamlining their workflow. Microsoft emphasizes that this advancement allows developers to utilize their familiar commands and workflows across multiple environments, such as Linux, macOS, and cloud platforms.
Coreutils is distributed as a single executable, requiring only one installation for various Linux commands, thanks to its architecture which uses a multi-call executable with NTFS hard links. As a result, this new tool simplifies administration by consolidating commands into one binary for installation and updates. Coreutils supports a total of 75 Linux utilities, including commands like ls, cp, grep, and find.
Nonetheless, there are some limitations: certain commands conflict with existing CMD or PowerShell commands, making them unavailable in Coreutils, including dir, kill, and whoami. Additionally, some commands can’t be executed due to dependencies on POSIX features that Windows doesn’t support. A compatibility table is provided by Microsoft to help users navigate these limitations.
At the conference, Microsoft also announced enhancements to its developer ecosystem, including the upcoming WSL containers CLI and API for deploying Linux containers on Windows, and new frameworks aimed at integrating AI agents within Microsoft 365.
