Suddenly this began to happen after a windows update (Windows 10). Every time I execute an ADB command for example, ADB devices the CMD pops up a new CMD window like for 2 seconds then closes up and doesn't shows me the results of the command.
I've uninstalled other android emulators that I had. Tried to Uninstall/Reinstall SDK but with no success. Tried to kill/start server. This continues happening.
I have the SDK up to date Rev: 25.0.4 I have made a video so you can see in a better detail what's happening.
