The Microsoft Windows 10 operating system includes support for configuring and managing your wireless network adapter. When you enable wi-fi for the first time on your PC, the adapter will scan the area for available networks and display a list of them on-screen, noting whether they require password security or not. Once you successfully connect to wi-fi, information about the network is stored in Windows so that you can rejoin quickly in the future. However, Windows 10 users have the option to remove or disable a wi-fi network at any time.
Step 1:
Right-click on the network icon in the task bar at the bottom of the screen and choose the “Open Network & Internet Settings” option.
Step 2:
Select the “Wi-Fi” tab from the left side of the window.
Step 3:
Move the slider bar to the “On” position if your wi-fi adapter is not yet enabled.
Step 4:
Click on the “Manage Known Networks” link. This will switch to a new screen with a list of all wireless networks that you have connected to from your PC. You can search or filer the list using the tools at the top of the window.
Step 5:
Highlight the desired wi-fi network and click the “Properties” button.
Step 6:
Move the “Connect automatically” slider at the top of the window to the “Off” position to disable automatic connections to the selected network. Then click the back button in the upper-left corner.
Step 7:
Highlight the network name again and click the “Forget” button to permanently remove the network information from the list.
After choosing to manually forget a specific wi-fi network on your PC, you can always use the “Show available networks” link to scan the nearby area and re-connect to it. For more information on managing wireless networks in Windows 10, consult this Microsoft TechNet article.
