I followed your instructions and applies it to Windows 7, Everything worked out fine.  And then, when I tried to make a short cut, the command line was incorrect.  With a little inventigation, I discovered window 7 uses "tasksch" instead "schtask" as used in step 5.  However, changing that part of the line didn't work either. So, a little more investigation, i found this "%Windir% preceeding the command for task scheduler.  Can you look into Step 5 for Windows 7?  I like to use this for my other programs.
