How can I optimise UAC on Vista 64?

Posted: 08-15-2008, 09:27 PM
Vista 64 SP1, fully patched.

When UAC kicks in, it's a real pain. Not that it kicks in but the way it
kicks in. The screen dims and the system is unresponsive for a couple of
seconds - just long enough for me to notice and then a bit longer. Then the
UAC prompt comes up. I'd like to remove the screen dimming and change it to
the sort of warning prompt you get when you try to run an ActiveX control or
Java applet. Can I do this?

Note that I don't want to disable UAC just modify the behaviour.

I think you're out of luck.

XdN Tweaker has an option for turning Secure Desktop off (what th
"blackness" is called). It works in both 32 and 64 bit flavors and yo
can get it here

There is also a way of doing it by modifying a registry entry but thi
is easier

That's called "Secure Desktop" and it can be disabled.

It takes a snapshot of your current screen, darkens it, and switches
to a secure desktop with the darkened screenshot as background.
Then it displays the prompt. It is not just fluff, it is a security measure.

You are probably not able to change this easily.

Yeah, that's a nice set of tools there. I like the UAC black screen disable.

It's a keeper, thanks.

Disabling the secure desktop feature of the UAC prompt
doesn't exactly "optimize" UAC - in fact it disables UAC
for any malware program smart enough to take advantage
of that change. Sure, maybe it is unlikely that a malware
program exists that can do this, but if enough Vista users
take this option - I'm sure some will be written.

You need to provide some proof here that disabling that black screen is
disabling the security functionality you speak about.

Here's the relevant excerpt:

"Securing the Elevation Prompt

The elevation process is further secured by directing the prompt to the
secure desktop. The consent and credential prompts are displayed on the
secure desktop by default in Windows Vista. Only Windows processes can
access the secure desktop. In addition to the recommendations for
administrators and standard users, Microsoft also strongly recommends that
the User Account Control: Switch to the secure desktop when prompting for
elevation setting should be kept enabled for higher levels of security.

When an executable requests elevation, the interactive desktop (also called
the user desktop) is switched to the secure desktop. The secure desktop
renders an alpha-blended bitmap of the user desktop and displays a
highlighted elevation prompt and corresponding calling application window.
When the user clicks Continue or Cancel, the desktop switches back to the
user desktop.

It is worthwhile to note that malware can paint over the interactive desktop
and present an imitation of the secure desktop, but when the setting is set
to prompt for approval the malware does not gain elevation should the user
be tricked into clicking Continue on the imitation. If the setting is set to
prompt for credentials, malware imitating the credential prompt may be able
to gather the credentials from the user. Note that this does also does not
gain malware elevated privilege and that the system has other protections
that mitigate malware from automated driving of user interface even with a
harvested password."
