On Windows 8, it was possible to forget a WiFi network easily via a simple right-click from the Network side panel. But since the update in 8.1, the task is more difficult. Indeed, the only way to make forgetting is when an attempt to connect fails. It is only then that Windows will suggest you forget it. Otherwise, prefer our method described in this article.
For this, do Windows+R, enter CMD then Entry.
Delete a WiFi network profile
Paste the following command line (Make Entry to validate each order):
netsh wlan show profiles
It allows you to list all WiFi network profiles saved on your PC.
To forget one, enter the command below, taking care to replace “profile name” with the name of the network to be deleted:
netsh wlan delete profile name=“profile name”
Remove all WiFi network profiles
If you want to forget all the networks in the list, then type the following command:
netsh wlan delete profile name=* i=*
A backlash from Microsoft inconvenient and surprising.
