Overview

This article provides the details on how to disable the User Account Control (UAC) on Microsoft Windows Servers. 

Process

Microsoft Windows Server 2008 

1. Select Start > Control Panel.
2. Select User Accounts > Turn User Account Control on or off.
3. Deselect Use User Account Control (UAC) to help protect your computer and click OK.
4. Reboot the machine for changes to take effect.

Microsoft Windows Server 2008 R2

1. Select Start > Control Panel.
2. Select User Accounts > Change User Account Control settings.
3. Move the slider bar down to the Never notify selection and click OK.
4. Reboot the machine for changes to take effect.

Microsoft Windows Server 2012 / 2016

1. Select Start > Control Panel 
2. Click System Security
3. Under Action Center, choose Change User Account Control settings
4. Move the slider bar down to the Never notify selection and click OK
5. Reboot the machine for changes to take effect

Note: Alternatively on All Microsoft Windows versions that support UAC - Fully Disable UAC from PowerShell as follows:

1. Select Start > Run
2. At the Run window type the following command and click Ok

   powershell

3. Copy/Paste this command in the PowerShell prompt: 
   

   New-ItemProperty -Path HKLM:Software\Microsoft\Windows\CurrentVersion\policies\system -Name EnableLUA -PropertyType DWord -Value 0 -Force

4. Reboot the machine for changes to take effect.
5. Make sure UAC is disabled by navigating to a restricted folder.
6. Select Start > Run
7. At the Run window type the following command and click Ok.
   

   C:\Windows\SysWOW64\Config

8. If the system doesn't prompt you for Administrative access - UAC has been successfully disabled.

Note: Often the UAC doesn't wholly get disabled, in Server 2012, by merely selecting Never notify in the user interface.  Instead, you will have to disable it in the registry fully.

Refer to this article "Windows Server 2012: Deactivating UAC" to disable via the registry.
