Single-Click to connet to VPN on Windows 10
I've solved it without need to mess around, so you can use option 1 since Windows 10 removed this checkbox:
- Open
%APPDATA%\Microsoft\Network\Connections\Pbk\rasphone.pbkin a text editor (Back it up first!) - Find
[YOURVPNNAME] - Find
PreviewUserPw=1- Change it toPreviewUserPw=0 - Save the file
Option 1 should now be working without a prompt.
