Hi,
Sharing photos in the new Windows 10 app is now much easier. Here's how. First, launch the Photos app and choose the picture you want to share or you can also right-click the image and select Share from the context menu. Clicking the Share button at the top will open the sharing menu where you’ll have different ways to share your media. You can choose Facebook here. The services that show up will vary depending on the apps you have installed and the format of the media.
