One empirical success to report is that we are now successful at opening a
red command window with white letters, where the reason for caring about
the color is to ensure that the user will always realize it's an "admin"
command window (yes, it says so on top also).

The solution for the red window was simple, as suggested by John Kerr-Mudd
in alt.msdos.batch, which was to use the "cmd.exe" "/color" option:

Adding that option to the INF file as shown below, worked fine:
HKCR,Directory\Shell\runas\command,,,"%11%\cmd.exe /T:47 /k cd /d ""%1"""
HKCR,Drive\Shell\runas\command,,,"%11%\cmd.exe /k cd /d /T:47 ""%1"""

Now the only thing left is to figure out how to modify the context menu for
the open admin command window to work no matter where you position the
mouse.
