How do you uninstall IIS and WAS (windows process activation service)? I've looked everywhere for information, and nobody seems to have instructions.

the same way you installed it - use turn on / off windows features.

If this happen when you try to map IsapiFilterModule which is native module type to a different issapi module like (php isapi ); IIS 7 automatically disabled the application pool associated with the domain/ default website. To solve this problem, simply
start the application pool through the IIS snap in --> Expan the Computer name --> Click on Application Pool to view the content--> Right Click on the application pool and click on start from the menu.
