Source: https://worklifenotes.com/2020/09/01/running-k3s-on-windows-with-wsl2/

Steps:

1. Install WSL2: https://docs.microsoft.com/en-us/windows/wsl/install-win10
2. Recommended: Setting CPU and memory limits to WSL2:
   1. Create the following file: c:\users<profile name>.wslconfig
   2. Content of the file (set CPU and memory limit as desired):

   [wsl2]
   memory=4GB # Limits VM memory in WSL 2 to 4 GB
   processors=2 # Makes the WSL 2 VM use two virtual processors
   

   3. Restart WSL2 (LxssManager Service). Run it in Powershell with Admin rights:

   Restart-Service LxssManager
   

3. Install Ubuntu 20.04 from the Microsoft Store. Warning: Install exactly this version. The method might not work for other versions.
4. For k3s you need systemd. To make it work in WSL, follwo the steps in the following heading.
5. After systemd is working in your linux distro, install k3s (following heading)
