I can open a picture in edit, just can't open it directly?!?

    Which image viewer have you set as the default? See if resetting Photos app as the default, via Control Panel > Default Programs > Set your default programs.

  • OK, I looked. The problem is that TWINUI doesn't work (and has been set as the default for most picture & video file types). I can change that, but advice on how to fix the error? Mar 27, 2016 at 20:21
  • TWINUI is actually the Photos app. I've posted an answer below.

Re-register/Reinstall the Photos app using PowerShell commands: Open PowerShell (Run as Administrator), and execute the following command:

Get-AppxPackage Microsoft.Windows.Photos -allusers | select PackageFullName

Note down the Package name shown. For example, if the Package name is listed as Microsoft.Windows.Photos_16.302.8200.0_x64__8wekyb3d8bbwe, execute the next command as follows:

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.Windows.Photos_16.302.8200.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode

As of now the Store apps are still buggy.. often requiring the user to run the PowerShell commands. For Desktops, better option is to enable the hidden Windows Photo Viewer and set it as default.
