Sure that works but its a strange way of doing it and the CPU usage is skyhigh
(37.7%) with my Intel i920 @ 2.67 GHz

Tested this:
"C:\Program Files (x86)\WinHTTrack\WinHTTrack.exe" -#9000000 

Right click icon on desktop, then choose properties.
Choose shortcut and added the command like this "C:\Program Files
(x86)\WinHTTrack\WinHTTrack.exe" -#9000000 but that didnt work.
