Thanks to Microsoft, Windows 8 doesn’t have an easy way to accomplish this same process. The link to modify or delete the connections is no where to be found. The only way to remove the connections in Windows 8 is to do so by using the registry editor.
1- To open the registry editor press the Windows + R keys to open the Run dialog, type regedit, and press Enter. If prompted by UAC, then click on Yes.
2- Go to this folder: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles.
3- The Profiles folder will provide a list of all the network locations (past or recent) that you have used. Each network location is represented by a subfolder.
4- Here you can delete individual sub-folders to remove individual connections or if you’d like to delete all the connections simply delete all of the sub-folders within the Profiles folder.
5- To rename a network location, click on the corresponding sub-folder and edit the key named ProfileName. Input the new name for the network location.
