On Windows 10, every time you connect to a Wi-Fi network a profile for that particular network with its SSID (Service Set Identifier), network security key, and other information will be created. In the future, if you want to connect, you simply select the wireless network, and Windows 10 will do the rest automatically.
The only caveat is that Windows 10 will save a profile of every network even if you no longer plan to use that particular connection. However, you can quickly delete (or forget) a wireless network in a number of ways.
In this guide, you’ll learn the steps to forget a Wi-Fi network on Windows 10 using the Settings app, Taskbar, and Command Prompt.
In order to delete previously configured and currently connected Wi-Fi networks do the following:
Click on Network & Internet.
Click on Wi-Fi.
Click the Manage known networks link.
Select the network you want to remove, and click the Forget button.
Once you’ve completed the steps, the Wi-Fi network you selected will be removed from your computer. If you need to remove other networks, simply follow the same steps.
You can quickly forget a wireless connection that you’re currently connected using the network flyout menu in the Taskbar.
Click the wireless icon in the notification area.
Right-click the network and select Forget.
After completing the steps, you’ll no longer see nor you will be able to connect to the same network unless you manually reconfigure it.
Alternatively, you can use the netsh command-line tool to remove one or all the network profiles stored on your device.
Search for Command Prompt, right-click the top result, and select Run as administrator.
Type the following command to identify the network and press Enter:
netsh wlan show profiles
Type the following command to remove the wireless network and press Enter:
netsh wlan delete profile name="WIFI NAME TO REMOVE"
netsh wlan delete profile name=* i=*.
Once you’ve completed the steps, the Wi-Fi network will be removed from Windows 10.
