How to do this in Windows 7:
1. Open the Control Panel
2. Pick "Network and Sharing Center"
3. Select "Manage wireless networks" from the left hand side
4. Highlight the profile and select "Remove"
That's pretty simple. Especially if you need to explain it to someone else. Say, for instance, someone who doesn't know about computers. Another method is to open the Start menu and type "manage wireless" and directly choose the "Manage wireless networks" entry directly.
Now, how do you do this on Windows 8? The same way? Nope. The manage networks option is suspiciously missing from the Network and Sharing Center.
Lets ask Microsoft how we should do this simple task:

I'll save you some time:
You're kidding, right?Some tasks, such as deleting a profile, must be done at the command prompt. To do these tasks, open Command Prompt, and then type the appropriate command from the following table.
Pretend you are using a Windows 8/8.1/RT tablet for a minute and let the absurdity of this procedure sink in. Sigh...At the command prompt, type:
netsh wlan delete profile name="ProfileName"
