Below is a breakdown of the differences between WSL1 and WSL2 WSL Version in Windows.

WSL1 is based on a compatibility layer between the Linux environment and the Windows kernel, rather than a full Linux kernel. As a result, it’s possible to argue that it’s not totally Linux. It’s a compatible Linux emulator running on top of Windows. In the WSL1 environment, however, most Linux binary executables execute without issue. It doesn’t support all of the Linux kernel’s system calls.

WSL2, on the other hand, is based on a full-fledged Linux kernel. It delivers full Linux kernel functionality without the need for an intermediary layer between the Windows operating system and the Linux kernel. In WSL2, all Linux system calls are fully supported. Some basic functions, such as I/O, are significantly faster in WSL2 than in WSL1.


WSL is a fantastic compatibility tool that lets users run native Linux apps on Windows without the need for virtualization or dual booting. WSL is now available in two versions: version 1 and version 2. Because it requires additional capabilities to run a full Linux kernel, WSL2 isn’t available on all versions of Windows 10. This article discussed two methods for determining WSL version, one from outside the WSL and the other from within the WSL environment.
