Before making changes, shut down the VM to ensure the settings apply correctly. Open or Command Prompt and run:

You should now see vmmem hovering around the limit you set, rather than consuming all available memory. Before making changes, shut down the VM to

WSL2 typically reserves of your total system memory for the virtual machine. If you have 16GB of RAM, WSL2 might immediately reserve 8GB–12GB for the Linux VM. If you have 16GB of RAM, WSL2 might

Since modern virtualization technologies (like WSL2 and Docker) run a real Linux kernel inside a lightweight utility VM, they require physical hardware resources (CPU and RAM). Windows cannot simply label this usage as "Docker" or "Ubuntu" because the processes are running inside a separate OS kernel. Instead, Windows aggregates the resource usage of that VM and displays it under the single process name: .

WSL2 uses unused RAM to cache files for faster performance within the Linux environment. How to Fix High Vmmem Resource Usage
