Change WSL2 Password

If you have forgotten your WSL2 password, this is how you change it.

Open the terminal.
Run wsl -l to see all distros and find the one you want to reset the password for. For example, we want to reset the password for user usr001 in the distro ubuntu-20.04.
```
wsl -l
```
Set default user to root. You must remove all -, . and whitespaces from the distro name.
```
ubuntu2004 config --default-user root
```
Open WSL2 and select a new password.
```
passwd usr001
```
Open the terminal again and set usr001 as the default user.
```
ubuntu2004 config --default-user usr001
```
