I have noticed around the forums and some replies I have gotten on some of my personal powershell issues that a command "Get-InstanceID" exists.
I tried using this cmdlet myself to no avail..I have read that this cmdlet was introduced in 3.0...yet I in fact have powershell 3.0.
It seems that my powershell doesn't have this command!
I'm not familiar with the command, but *most* commands are not native to PowerShell. They are added in, usually as modules. That is almost always true when they relate to some external product. For example, Get-ADUser is not a native Windows PowerShell command; it comes with specific versions of the Windows operating system.
