In cmd.exe: wsl -u root. This logs you in as root in Linux. There from you are free to change password as usual with: passwd username

Test locally with (wildcard) subdomains

Do nothing if your user-agent is Chrome, IE, Firefox. They connect to localhost with http://*.localhost:post

Edit /etc/hosts or C:\Windows\System32\drivers\etc\hosts: Append lines like

127.0.0.1 example.com
127.0.0.1 subdomain1.exmaple.com subdomain2.example.com

Squid should automatically start running. Check with : systemctl status squid.service
Now edit config : /etc/squid/squid.conf as described below

	1. Open "Turn Windows Features On or Off"
	Check "Windows Subsystem for Linux" & "Virtual Machine Platform"
	Restart

	2. Install "https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi"
	[Ref: https://docs.microsoft.com/en-us/windows/wsl/install-win10#manual-installation-steps]

	3. In cmd.exe or PowerShell: wsl --set-default-version 2

	4. Install Linux distribution of choice from MS store or if to upgrade existing distro from WSL1 to WSL2:

	#!/usr/bin/env bash
	# Brief: Given any IPv4 address check if it is private or public. IPv4 itself is not validated
	# Exit code: 0 (private); 1 (public); 2 (neither private nor public)
	# Usage: ipcheck <ip_addr>

	_test(){
	# Brief: Test if given value if within given limits. No output. Just exitcode.
	local limit1="${1}" value="${2}" limit2="${3}"
	[[ "$(echo -e "${limit1}\n${value}\n${limit2}" \| sort -V \| awk NR==2)" == "${value}" ]]
	# TODO: May be `-V` is not needed in `sort`
