How to manually forget (delete) a wireless network in in Windows 8.1.

Unlike the Windows® 8 operating system, the Windows® 8.1 operating system does not provide the ability to right click on a previously connected wireless network profile and give you a Forget this network option. If you wish to forget (delete) a network profile from the Windows 8.1 operating system, you will need to do so from within a Command Prompt window.

Follow these steps to open a Command Prompt window and forget a network profile.

1. Open a Command Prompt window  with administrator rights.
2. In the Command Prompt (admin) window:
   • To display a list of the networks that you have previously connected to, type netsh wlan show profiles.
   • To remove or forget a network, type netsh wlan delete profile [wireless network name].

   • NOTES:

     • Example: c:\windows\system32>netsh wlan delete profile linksys
     • Typing the example command above and pressing the Enter key will return the message Profile "linksys" is deleted from interface Wi-Fi.
   • To delete all networks that you've previously connected to, type netsh wlan delete profile *.
     
3. Click the X in the upper right corner to close the Command Prompt (admin) window.
