wamp server asking password in xp

Recently when I try to start the wamp server in my freinds laptop I faced this problem. And sharing the solution for that problem here.

The reason for this may be because of running IIS server in your system. To solve this problem either disable the IIS server. Follow below steps to disable IIS server.

1. Goto control panel
2. Goto Add/Remove programs
3. Goto Add/Remove Windows components
4. Uncheck IIS

Then restart the wamp server. This time it wont ask for the password.
