Windows – Allow dropbox through windows firewall when everything else is blocked

By default, Windows Firewall with Advanced Security allows all outbound network traffic.

To block the network traffic for prohibited programs, you must create an outbound rule that blocks traffic with specific criteria from passing through Windows Firewall with Advanced Security.

Alternatively, you can change the default outbound action to block, and then create outbound allow rules to allow required traffic. This technique is demonstrated in this TechNet article.

To solve this, you need one of two options:

• Use %APPDATA%\Roaming\Spotify\Spotify.exe OR
• Use C:\Users\username\AppData\Roaming\Spotify\Spotify.exe

As well, you might want to block the SpotifyWebHelper.exe application for incoming traffic which might be also used for P2P.
