I am trying to use WAMP on Windows 7, my WAMP is online, but when I open localhost I get the welcome page of IIS 7.5, although I have uninstalled IIS 7.5 from my PC!
Go to Control Panel > Administrative Tools > Services or simply type
services.msc in run to open a list of all windows services.
Find World Wide Web Publishing Service and stop it. (if you want to disable it permanently you can change its start up type from automatically to disabled).
