Windows Subsystem for Linux (WSL)

Allows using Linux directly in Windows, without double booting or virtual machines.

WSL 1 WSL 2
Architecture Syscall translation Real Linux kernel in lightweight VM
Linux compatibility Partial Near-complete
Kernel No Linux kernel Full Linux kernel
Docker support Unsupported Required / native
Filesystem (Linux files) NTFS ext4 (virtual disk)
Linux I/O performance Slower Much faster
Windows file access (/mnt/c) Faster Slower than WSL 1
Networking Shared host IP Virtualized network, separate IP
System services Limited Fully supported
cgroups / namespaces Not supported Fully supported
Resource usage Lower overhead Slightly higher, dynamic
Use case Legacy / Windows-centric Modern Linux development
Recommendation Avoid Default choice

Commands

Ran in windows powershell, NOT the linux terminal.

# The actual version of each installed distro
wsl -l -v

# The default version for newly created distros
wsl --version

# Forces the chosen distro to run under WSL 2. Converts it from WSL 1 if applicable.
wsl --set-version Ubuntu-24.04 2

# Sets WSL 2 as the default for newly created distros only. Does not modify existing ones.
wsl --set-default-version 2

# Updates the WSL kernel and components used by WSL 2. No effect on WSL 1 distros.
wsl --update

# Stops all running WSL distros and the WSL virtual machine. Clears state. Required after version or kernel changes.
wsl --shutdown
