does windows vista home premium have IIS?

Answer 1

This is a pretty interesting question. I would think that anybody that would ask about Internet Information Server should know this answer right away.

I don't think it is Microsoft idea to have a web server, or web services running from a Home version of an OS. Regardless, you're lucky that it can be done. It is not installed by default, and you can install it following Microsoft's instructions.

Answer 2

Go to Microsoft's website and compare all versions of Vista.
