I had a problem with the reg mod at: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
It worked to get the voice recognition working, but on my first reboot I discovered I had lost my quickstart menu. After reestoring the QS Menu voice recognition still worked. So I thought, GREAT, I've got it!". Next reboot? Same thing! I disabled ctfmon.exe useing msconfig, rebooted and all is well, except, of course, I have no voice recognition. Ah well, it didn't work worth a damn anyway!
