http://localhost/ not working on Windows 7. What's the problem?

Question

I have a big problem opening http://localhost/ on Windows 7 (beta). I installed this os and everything went great; when I installed Wamp I saw that localhost is not working

Answer 1

To fix the port 80 problem do:

From cmd as administrator:

1. sc config http start= demand (you need a space after the equal sign and not before)
2. Reboot
3. Run the command (netsh http show servicestate) as administrator to check that the port 80 is in use

After you have run this command, you can disable http.sys as follows:

1. net stop http (stop the process)
2. Sc config http start= disabled (if you want to disable the service forever)

it works for me.
