[Windows] Scan hosts for open ports without Telnet with PortQry

When testing a connection, you'll probably want to check if a particular port is reachable on the destination host. Telnet is fine enough for this task:

telnet host port

but unfortunately, Windows comes with the Telnet client disabled by default. Since enabling it requires you to have Administrator privileges, an alternative is to use Microsoft PortQry which is a command line tool with no installation required.

After downloading and extracting it, you can run it as:

portqry -n host -e port
