To Stream content from a Geo-Restricted site, first of all, you will need to know which country the content is geo-restricted to. For example, if you want to watch The Office (US), it is currently only available on Netflix Canada, so this is what you should do:

1. Open the Windscribe app on your device.
2. Select Canada from the server list and connect to one of the Canadian locations.
3. Once the VPN is connected, open the Netflix website or Netflix app.
4. Select the content you want to stream.

It is as simple as that for most of the major streaming sites, including geo-restricted sites. Sometimes you will need to restart the streaming app or close and re-open the streaming website's tab in order to fully reload it.
