How do I stop IIS7.5 starting by default?

Solution 1:

You have to disable two services:

• World Wide Web Publishing Service (W3SVC)
• IIS Admin Service (IISADMIN)

Go to Services, properties of the above mentioned services, change the start up type to "Disabled"

Enjoy.

Solution 2:

Look for World Wide Web Publishing Service (W3SVC) in services.

Also you could change the default port into something that does not conflict with Apache?

Solution 3:

1. Hit Windowskey-R (or click start -> run).
2. Type in "services.msc"
3. Double Click "World Wide Web Publishing Service" to view its properties
4. On the first tab "General" you'll see a "Startup type" drop down box, set it to "Manual" or "Disabled".
