How to create a .wslconfig file?

I have installed WSL2 on my Windows 10, but I would like to set up a .wslconfig file in my C:\Users\username folder, with the following instructions:

[wsl2] localhostForwarding=true

I have tried to create a notepad, putting the above in and saving the file as .wslconfig. However, it is still being read as a .txt file rather than .wslconfig. This was the instruction on how to create a .wslconfig file that I read online.

I added a .ini extension, doesn't seem to be detected.

I have tried to find what the error might be. I looked at https://github.com/microsoft/WSL/issues/5170 I am build 19043

I just set up a .wslconfig file on my machine.

As an administrator (probably not needed though), I created the file c:\Users\damie\.wslconfig with the following contents:

[wsl2]
memory=20GB # Limits VM memory in WSL 2 
processors=4 # Makes the WSL 2 VM use 4 virtual processors
localhostForwarding=true # Boolean specifying if ports bound to wildcard or localhost in the WSL 2 VM should be connectable from the host via localhost:port.

After saving, I opened an administrator level powershell windows and executed:

Restart-Service LxssManager

This worked for me.

Sample of .wslconfig file can be found here. Manually create the file at C:\Users\user, copy the contents and update as per requirement. All the guided steps are mentioned in the docs link above.

Notepad saves files as TXT by default. If you don't want a TXT, Save as type > All files
