Thanks Brink and Logicerth for the useful info , both of you did answered my question.
Just for additional share info. I have figured out how to look up the version of IIS currently installed on your Windows 7 PC, where as soon as you have IIS Manager opened , you can basically click on Help and about. It is going to tell you the exact version of IIS you are running on the PC.
Here is the exact Steps:
1.) Go to - Control Panel
2.) select Administrative Tools
3.) double click on Internet Information Services (IIS) Manager
4.) Once the IIS Manager opened , click on "Help" and then select "About".
Thanks for all of your help.
