Goal: You want to use DSC to disable UAC (User Account Control) completely.
Scenario: You are using PowerShell version 4 and Windows Server 2012. (The solution may work for different versions.)
You tried to use the configuration found here:
Import-DSCResource -Module MSFT_xSystemSecurity -Name xUac
Setting = "NeverNotifyAndDisableAll"
When you run the above as a .ps1 file, you will see a message that says "Unexpected token '}'" error. When it happened to me, I tried moving the "Import-DSCResource" to be under the "Node" section. When I ran the .ps1 file, I received a message about "The term 'Import-DSCResource is not recognized..."
Solution: Leave the code alone except for one change: eliminate the "MSFT_" portion.
