Vista - Turn off screen blackening with User Account Control?

Hi

Running Vista Ultimate and have two displays attached (EIZO CRT). Each time
User Account Control asks me if I realy want this or that (which I think is
good), the screen gets that black overlay or transparancy. This switch makes
my second display switch mode, which means a hard click sound, screen goes
off and then on again. This is realy anoying, so I turned UAC off.

Is there a way to change this behavior?

I doubt it. This isn't just an overlay. It's a whole different desktop,
running as a different user, with a picture of your desktop in the
background to make it a bit more seamless. The prompt doesn't happen under
your credentials.

No, it can be done. That is secure desktop you are seeing. All you have to
do is disable secure desktop. However, be warned that this does present a
security risk. UAC prompts must be answered by a human, no other process or
script can hook in and answer for you because the prompt is opened in a
whole new process.

Ok, on to the answer:

Type "secpol.msc" in the Start search box.
Press "enter"
Accept the elevation UAC dialog.

Under "Security settings", open tree "Local policies"
Click "Security Options"
Scroll down to:
"User Account Control: Switch to the secure desktop when prompting for
elevation"

Right click on it.
Click "Properties" On the "Local Security Setting" tab:
Select "enable"
Click OK
Close the "Local Security Policy" Application. You're done!

Hi

Thanks for the answer. Can you explain what the difference is between
disabling UAC? Because what I did was just disabling UAC, but in a different
way then you described below. So what is disabling Secure Desktop exactly?

Hello,

Disabling UAC turns off all the benefits of UAC.

Disabling the secure desktop transition keeps UAC enabled; however, the
screen doesn't blacken.

This does reduce security somewhat. The reason UAC blackens the screen and
switches to the "Secure" desktop is to prevent evil programs from pretending
to be you and clicking the Continue button automatically.

By turning off the secure desktop, you run the risk of this happening.
