Disable or quiet UAC without reboot from command line

Question

I need to be able Disable or quiet UAC without reboot from command line without user confirmation as local system
We use LANDesk and I want to add a part of the script to install turning off or quieting UAC, run install and them turn UAC on
Not all users are Admins so I can run as current logged on user but if admin rights are not need I can run a pre install task as local user run the
install task then run a post install task to turn it on
It doesn’t have to be a command line it can be an app Ii position on each machine then call if it can run silently

Hi,
Thanks for posting in Microsoft TechNet forums.
To disable UAC, you can take either of the following methods:
1.    
If you use Group Policy to manage UAC, you can edit the local security policy to control this:
1)   
From the Start search bar, type "Local Security Policy"
2)   
Accept the elevation prompt
3)   
From the snap-in, select Security Settings -> Local Policy -> Security Options
4)   
Scroll down to the bottom, where you'll find nine different group policy settings for granular configuration of UAC.
2.    
Use the following script to elevate the privilege in Windows Vista.

3.    
You can also modify the registry through the following command line:
REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0x0 /f
Important caution:
please backup your registry before modifying it, any incorrect modification can cause a unrecoverable damage.
