How to close a selected instance of Internet Explorer

Yesterday in my PowerShell class we were doing a lab on object enumeration.  I took a few minutes to take a look at the forums on PowerShell.com and found a question that related directly to our lab content.  Here is the scenario.

This individual needed to close an instance of Internet Explorer.  The problem is that there were multiple instances open.  He needed a way to select a specific instance.  Using the Get-Process cmdlet, you can grab each instance, but the process object does not contain anything useful to isolate a particular instance. So I tried a different approached.

I opened an IE instance and went to PowerShell.com.  I then executed the code below.

(New-Object -COM "Shell.Application").Windows() |
    Where-Object LocationName -like "PowerShell*"

Here is the result.
Application          : System.__ComObject
Parent               : System.__ComObject
Container            :
Document             : mshtml.HTMLDocumentClass
TopLevelContainer    : True
Type                 : HTML Document
Left                 : 56
Top                  : 161
Width                : 936
Height               : 641
LocationName         : PowerShell.com – PowerShell Scripts, Tips, Forums, and Resources
LocationURL          : http://powershell.com/cs/
Busy                 : False
Name                 : Internet Explorer
HWND                 : 1249664
FullName             : C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE
Path                 : C:\Program Files (x86)\Internet Explorer\
Visible              : True
StatusBar            : True
StatusText           :
ToolBar              : 1
MenuBar              : True
FullScreen           : False
ReadyState           : 4
Offline              : False
Silent               : False
RegisterAsBrowser    : False
RegisterAsDropTarget : True
TheaterMode          : False
AddressBar           : True
Resizable            : True

Examining the LocationName property, I can see that I am referencing the correct instance.  Next, I sent the object to Get-Member.
    TypeName: System.__ComObject#{d30c1661-cdaf-11d0-8a3e-00c04fc9e26e}

There is a Quit method.  In class, we are using ForEach-Object to execute object methods, so I just added a little code from class.

(New-Object -COM "Shell.Application").Windows() |
    Where-Object LocationName -like "PowerShell*" |
    ForEach-Object -MemberName Quit

This closed the instance of IE that was on PowerShell.com.  I also did this when PowerShell.com was opened in a tab among several other websites in the same instance.  No problem.  Only that tab closed.
