Default Web Site not found in IIS 7

I recently had a problem that i couldn't find the "Default Web Site" under Sites tree view in IIS 7 and i found the solution too.

To Solve this we have to re install the IIS and WAS (Windows Process Activation Service)
To do this,

• Go to Control Panel
• Make sure the View By filter is set to "Category"
• Click the Program link
• Under the Programs and Features click "Turn windows features on or off link"
• A window will popup
• There uncheck the Internet Information Services and Windows Process Activation Services checkbox
• Restart the system
• Then recheck the check box you have unchecked(IIS & WAS)
• Now check the Default Web Site in IIS, that will be there!
