How to determine what version of Citrix XenDesktop is installed in an environment

I’ve noticed recently that I’ve been asked about how to determine what version of Citrix XenDesktop is installed in an environment so I thought I’d quickly write a post to demonstrate this.  First off, I don’t think there is a way to determine the version in Desktop Studio as I’ve been unable to find this information in the past when I browsed through the GUI so the way to do it is to use the PowerShell cmdlet:

**Note that the 2 screenshots above is Update 7.
