Windows 10 automatically connects to a Wi-Fi line you've already used. A feature that can create security issues, here's how to disable it
By default, a Windows computer will automatically connect to previously used Wi-Fi networks. This is a convenient but not always useful service. Sometimes, in fact, we may need to change Wi-Fi networks. Luckily, in Windows 10 you can block the automatic connection.
If we enable the connection blocker, Windows won't forget the network and the password needed to connect, but will simply wait for us, manually, to decide to associate with that particular wireless line. Blocking the automatic connection is also an important choice for computer security. If, for example, one day we were to connect to a public line, if we were to pass by that area with the notebook on, the PC could automatically connect to the Net, exposing us to various cyber threats. Free Wi-Fi connections, in fact, are the ones most targeted by cyber criminals.
Break the automatic connection on Windows 10
To block the automatic connection on Windows 10 we'll have to manually stop every single Network to which we don't want to connect without our will. Basically we just need to click on the Wi-Fi symbol, present in the taskbar in the bottom right corner, and select the name of the network we want to block. As we select the connection two options will open: one related to Properties and the other to disconnect. We must click on Properties. At this point a new page will open and we will have to uncheck Enabled from the Automatic connection item (it is the first section at the top). In this way the computer will no longer connect to that network, unless we decide to do so. To manually connect to a deactivated network we don't need to take the long way around, i.e. Settings> Network & Internet> Wi-Fi, but we'll just have to click on the name of the connection (always after clicking on the Wi-Fi icon in the taskbar) and then select Connect.
