That's because autodetection for the URI doesn't work with remote
drivers only. You cannot guess the server name.

Well, you can do that with a simple batch file:

@echo off
set /p uri="Enter libvirt connection URI: "
virsh.exe -c %uri%
pause

Put that in a virsh-launcher.bat in the same directory as virsh.exe
and link to it.

The set /p command outputs the prompt string and lets the user input a
line of text and assigns it to the uri variable. The pause at the end
stops the command window from closing automatically when virsh exits.

You might add some informative output before the set /p using echo.
