Hi,

you can set the EnableLUA Value in the Registry(HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System) to 0 to disable and to 1 to enable.

Answer 3

Be aware that a reboot is in order after UAC is toggled.  Therefore you can't simply toggle the registry and enable/disable the feature.  That also means that the existence (or lack therefore) is not sufficient to detect whether UAC is enabled since a pending reboot might be in order.

Answer 4

So does that mean that he cannot enable and disable UAC of vista at runtime by programmatically?

Answer 5

You can change it programmatically although the approach is undocumented.  However it does not take effect until a reboot occurs.  Furthermore if UAC is enabled then you won't be able to change it without a UAC prompt.

Answer 6

Thanks TaylorMichaelL. I found a tool that let me disable UAC and will let it stay disabled even after a reboot . They call it "bye bye uac". Do you have an idea how they manage to do this?

Answer 7

As was mentioned earlier in the thread a registry entry can be set to disable UAC.  However, it does not take effect until a reboot.  Once you reboot UAC will be enabled or disabled and remain so until it is changed again.
