[Dailydave] Vista speach recognition

[Rich Mogull]

I just tested this on Vista and it works.

Running Vista Ultimate in Parallels on my Mac I enabled voice  
commands, then recorded a simple command and played it back. Using  
the mic and speakers on my Mac the commands executed. Sound quality  
was actually terrible because of poor Vista performance in the VM.

But UAC seems to stop it. At the suggestion of Dave Maynor I tried to  
create a new user account. The usual UAC window popped up and no  
voice commands seemed to work.

I suspect anything that avoids the "final" (greyed out background)  
UAC dialogs will work, but looks like UAC stops it. At least in my  
quick test...
