Install Desktop Experience On Windows Server 2012

Install Desktop Experience On Windows Server 2012

Update 28-10-2013:  Added PowerShell example to install Desktop Experience

 

While working with one of my consulting colleagues recently on some Windows Server 2012 installations.  There was an application requirement to install Media Player onto a couple of the servers.  This met with some muttering and cursing from the nearby fabric covered box as the option to install the Desktop Experience feature is not as obvious as it was on Windows 2008 R2, highlighted below. 

Windows 2008 R2 Add Features - Desktop Experienced Highlighted

Using the GUI To Install PowerShell

I’m sure there is an oxymoron in there if you look hard enough!!  If you want to just drive the GUI to install the Desktop Experience feature through Server Manager you have to expand the User Interfaces and Infrastructure feature and select the Desktop Experience component.  So yes, it’s a little bit more hidden but you don’t have to be Indiana Jones to discover it.. 

This is shown in the screenshot below:

Installing Desktop Experience Using PowerShell

So that’s all nice, but what if we did not know that the Desktop Experience feature was located in that area?  PowerShell to the rescue!!!!

 

Probably my favourite installation features in Windows Server 2012 are the Get-WindowsFeature and Install-WindowsFeature cmdlets. 

What makes these cmdlets even more powerful, is that they accept wildcards as input.  So in our case we can look for something called *Desktop*

Get-WindowsFeature *Desktop*

Windows Server 2012 Get-WindowsFeature

That’s pretty neat, and we can then see exactly where the Desktop Experience feature is located.  The same goes for the GUI options that are present in Windows Server 2012 R2: 

 

Windows Server 2012 Get-WindowsFeature

 

We could then install it via Install—WindowsFeature

 

So as an example, we could use the following PowerShell oneliner to install Desktop Experience:

 

Install-WindowsFeature Desktop-Experience

 

 

For those folks out there who used the Windows 2008 R2 cmdlets, you will have noted that I specified Install-WindowsComponents above and not Add-WindowsFeature.    

 

Windows Server 2012 Add-WindowsFeature Alias

This is because the cmdlet is Install-WindowsFeatures and Add-WindowsFeature is an alias to Install-WindowsFeature.  We can see this with the Get-Alias cmdlet:

Windows Server 2012 Add-WindowsFeature Alias

Checking Computers Remotely

Using wildcards is neat, and can make administration quicker and faster. What makes this even more efficient is that Windows 2012 now has a ComputerName parameter so we can directly query a remote machine.  Additionally we do not have to manually import the ServerManager module in Windows 2012 either.  In the example below DC-1 is the local machine which then queries a remote computer called Server-1:

Windows 2012 Get-Windows Feature - Querying a  Remote Machine Using -ComputerName

Installing PowerShell On Upgraded 2008 R2 Core Server

PowerShell is not installed by default onto a Windows 2008 R2 core installation.  Most customers will install it unattended or manually since the addition of PowerShell was a great new Feature in Windows 2008 R2.  One of the machines that was previously upgraded did not have PowerShell enabled on 2008 R2 and after the upgrade to Windows 2012 it was still not fully enabled.  

OCLIST on 2008 R2 will show us the initial state, prior to upgrading

Windows 2008 R2 Prior To Upgrade - No PowerShell Installed

 

On Windows 2008 R2 the Sconfig tool was one way that PowerShell could have been enabled.

I noted that a clean 2008 R2 Core VM when upgraded to 2012 was not able to run PowerShell as the feature was not present. 

Attempting to Run PowerShell On Upgraded Server Core Machine

Checking the installed components locally with DISM showed

 

Dism.exe /Online /Get-Features

 

Using DISM To Show Installed Features

 

Checking the installed components remotely shows that the PowerShellRoot is installed, but PowerShell itself is not installed. 

To Check remotely from PowerShell we can use a separate machine, and we specify the –ComputerName parameter with the name of Server-10 which is the name of the upgraded 2008 R2 core machine. 

 

Get-WindowsFeature To Check Installed Components Remotely.  PowerShell Not Installed.

Compare this to the below (a server with the GUI installed) and note that PowerShell is installed on the example below but not on the upgraded server shown above.  

Get-WindowsFeature To Check Installed Components.  PowerShell Is Installed.

 

Since PowerShell is not installed we cannot use Add-WindowsFeature to install It locally, since it’s chicken and egg time…. 

DISM is still present so we can enable the feature using it:

DISM.exe /Online /Enable-Feature /FeatureName:MicrosoftWindowsPowerShell

 

Using DISM To Install PowerShell

Alternatively we could have used a remote Server 2012 machine, and specified the upgraded box using –ComputerName and installed PowerShell that way.  This is shown below along with the –Restart parameter which automatically restarts the machine if required:

Windows 2012 - Remotely Installing PowerShell

 

Logging off and back on to re-spawn the cmd prompt then allowed PowerShell to be launched. 

Conclusion

One little cmdlet, but it’s so very powerful.  You could change the above syntax to suit your requirements.  PowerShell will show you the name of the feature, and now you can add it remotely and also restart the target machine when the installation is complete.  As Bill & Ted would say – Excellent!! **

** PS – Looks like a third film is planned.  Hopefully this will be better than the proposed Highlander reboot……

  • Could you please provide a "install-windowsfeature" code sample?

  • Hi Peter

    You want this sample to be for the Desktop Experience feature specifically?  

    Cheers,
