Disable UAC without reboot?

[Max]

Does anyone know how one might disable UAC without reboot. I'd like to
be able to disable it via the registry (I'm familiar with how to do
this) and possibly run something that simulates a reboot? I know the
tool TweakUA does this so there has to be a way. This is for the
purpose of supporting Windows Vista clients with VNC and having a
simple way to disable then re-enable UAC when finished.

Thanks,
Max

Instead of disabling UAC completely, it's best to disable the Consent Prompt
Behavior for Admin accounts.

All of the UAC settings are contained in the following registry Key.

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

The Value 'ConsentPromptBehaviorAdmin' is what you are looking for. Note
the default Value Data is '2'. Change this value to '0' (Zero).

You should make a backup of that System Key prior to making any changes.

One thing to remember is that when you do disable UAC, you also lose the
File, Folder, and registry virtualization as well as Internet Explorer
Protected Mode and much of the compatibility for older software. If you will
be installing programs with UAC turned off, when you do turn it back on, you
may experienced some unexpected behavior from these programs.

Why would you want to? If it takes much longer than a minute or so to
reboot then something is wrong with your setup.

If fact if you use your computer intensively for hours on end
switching between a lot of different high demand applications is
actually helps to reboot after several hours of use since this is the
only way to flush out some of the crap Windows has in memory and as a
bonus it refreshes system resources which may be getting depleted.

Ronnie -

Does this setting require a reboot? And will this stop the
connectivity being cutoff when using remote control programs like VNC?

Thanks,

No, this does not require a reboot. This is the advantage of changing the
settings via the registry. Press the F5 key before you exit regedit to
refresh.

I don't know the answer to the question about VNC, you'll just have to try
it.

IF you use Group Policies (or edit the registry) to set UAC to still
notify, but NOT use a secure desktop, it won't kill VNC.

Would it not have been quicker to reboot than to write and read the
responses to this post?

What are you using man? A celeron with 32 MB of ram? Is it like an
all day job to do a quick reboot?

Far more important when you're supporting remote machines via VNC -- You
cannot turn off UAC as turning off UAC requires a UAC popup.
