windows 8windows 8.1
In Windows 8.1, when I right click a WiFi connection, nothing happens. In Windows 8, there is a menu and I can view its properties by clicking the "View Properties" menu item, and then I can see the password for that WiFi connection.
How to do the exact same thing in Windows 8.1? And also how do I tell the OS to forget certain WiFi connection?
Right click the Network icon in taskbar. In the dropdown menu click 'Open Network and Sharing Centre'. It will show you your current connections. In the windows that appears, click the highlighted link in the snip. 
In the new windows that appears, click on ' Wireless Properties'. Your are on your WiFi network properties window !
This is something they took out in Windows 8.1.
Essentially, you will need to connect to the network at least once and then, if it fails, it will prompt you to be able to forget it. Unfortunately, this is not at all easier.
If you are itching to do it manually, you can use the Command Prompt.
Start the Command Prompt with Admin rights, and type netsh wlan show profiles. It will display all the wireless network profiles stored by Windows 8.1. The list can be long if you used your laptop or tablet for more than a couple of weeks.
Identify the name of the wireless network profile you want removed, then type the following command to remove it: netsh wlan delete profile name="profile name".
As an example, I wanted to remove a wireless network profile named swisscom and I typed: netsh wlan delete profile name="swisscom".
