Check if RSAT is installed with this one-liner

You are installing RSAT in a build, and you want to check if it is installed if it is included in the windows updates. Recently, there has been the issue in Windows 10 where RSAT cannot be found in the Windows Features. It is also not found in the Win32_OptionalFeature. To work around this, I have this one-liner incorporate checking for the feature first and if that turns up nothing, it then checks for the active directory module, which exists if RSAT has been installed. It will return an exit code of 0 for success and 1 for failure which can be used to either pop up a warning or kill a build if not present. This has been tested on both Windows 7 and Windows 10.

powershell.exe -command "&{If ((Get-WmiObject -class win32_optionalfeature | Where-Object { $_.Name -eq 'RemoteServerAdministrationTools'}) -ne $null) {Exit 0} else {If ((Get-Module -Name ActiveDirectory -ListAvailable) -ne $null) {Exit 0} else {Exit 1}}}"
