Hi There,

I'm using Windows Vista Ultimate ( dutch ) and always when I click on
something
I get the UAC ( user account control ).

That's not the problem but almost 75% of my screen gets black so I can't see
the warning popup. How can I fix this?

Kind Regards,
Michi

Click on Start, Control Panel, and then click User Accounts and Family
Safety.

Click on "User Accounts", and then you should see "Make changes to your user
account" and a list of tasks. From this list, click "Turn User Account
Control on or off".


Hope this helps.

When the UAC prompt is displayed, it is running on what is called a 'Secure
Desktop'. While the secure desktop is displayed, your main desktop is
'dimmed', with the exception of the item that caused the UAC prompt (so you
know what did it). That's assuming that you are running with the full Aero
enabled, it's slightly different is you are running Aero Express.

The Secure Desktop is there to stop a malicious program 'spoofing' it, and
attempting to capture admin credentials.
 
That's not fixing the problem, it's disabling UAC. Kinda like fixing a
smeared windscreen on your car by removing the glass - you can see better,
but you'll get a lot of bugs in your teeth. ;)

Turn up the brightness on your monitor.

Try this:

Start Menu>type "gpedit.msc" in the Search bar, click it>
Computer Configuration>Windows Settings>Security Settings>
Local Policies>Security Options

Scroll all the way to the bottom, should be the second to last option;
"User Account Control: Switch to the secure desktop when prompting for elevation"
double click it.
Check Disabled.

You will still receive the UAC prompts, but your desktop will not freak out
and do the black screen jig.

Here's a short video on how to do this.

..... if you don't have Vista Business or Vista Ultimate, you can achieve
the same by changing the value of

PromptOnSecureDesktop

at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

from 1 to 0

Thanks, Jon. I added that tip to the saved document I use to cut and paste
the tweak on UAC.... makes it so much easier than typing it out all the time.

Take care,

yw.. hope it works. ;-)

I believe that's the right setting, but I haven't fully tested it eg a
reboot may be required etc.

Whilst that turns the secure desktop off, it completely removes one of
the major benefits/securities of UAC.

The secure desktop is separate, and user code cannot run on it. If you
disable this, then standard user applications can interact with the UAC
prompt - specifically clicking OK for you!

Also, there's no longer any guarantee that the UAC prompt which comes up
is actually a real UAC prompt and not a 3rd party look alike which then
captures your admin username/password.

Running UAC with a secure desktop is the best way. Only disable it if
there's a real problem (like external monitors getting freaked out and
not syncing properly afterwards etc).

He asked a question I answered. Besides, "the best way" can be
more subjective than objective. There are *no* "guarantees" about
UAC one way or the other.

However, you are correct in bringing this to the OP's attention and
to others. All options and their possible consequences should be
put on the table.

I have UAC turned off. That's my prerogative, it's the best way for me.
I don't suggest that other users do this. But, I do because it's the way I
want *my* machine.


Take care,

Michael
 
Understood. I mis-read the intent of the poster.

But it appears the others got him pointed in the right direction.
