Detailed Description of the Pull Request / Additional comments

Currently, WSL Starting Directory is /mnt/c/WINDOWS/system32, it's better to be in /mnt/c/Users/UserName directory.

This only take effects if no existing profile.

This seems reasonable to me. Ideally we'd set it to the linux home path, but since we can't possibly know that when these are generated, and we can't just set it to a linux path directly, this seems like a good and righteous change to me.

I have an up-to-date version of the terminal, but still get the system32 path by default for my Ubuntu wsl. What should I do to change this behavior to match the one proposed in the above PR?
