Enable Windows Photo Viewer in Windows 10

Those you who have upgraded from Windows 7 or Windows 8.1 to Windows 10 probably have Windows Photo Viewer program in Windows 10. But some users are reporting that Windows Photo Viewer has gone missing after clean installing Windows 10.

If you are missing the Windows Photo Viewer, we can bring back the classic Photo Viewer to Windows 10.

  1. Copy and paste the following registry key and save as PhotoViewer.reg:
    Windows Registry Editor Version 5.00
    ; Change Extension's File Type
    ; Change Extension's File Type
    ; Change Extension's File Type
    ; Change Extension's File Type
    ; Change Extension's File Type
    ; Change Extension's File Type
    ; Change Extension's File Type
  2. Double-click on the saved PhotoViewer.reg file.
  3. Click Yes button when you see the following confirmation dialogue to merge it. Alternatively, you can right-click on it, and then click Merge option.
  4. Click OK button again when you get the following dialogue box and that’s it! You have just enabled the classic Windows Photo Viewer in Windows 10.
  5. Optionally you can also make it default for images.

Mac Spotify: Cannot Start Application

So you want to run Spotify.app on macOS with multiple users environment but it says that you ‘Cannot Start Application’

Multiple users environment is where you have one Mac, and it has more than one user using it.

Spotify updated their app and prevent us running the app from another user (it will only run on the user who installed it)

Since their previous version doesn’t have this issue, I investigated the issue and found out that it was caused by permission issue.

The following are the resolution:

  1. Download and install Spotify as normal;
  2. Quit the Spotify Application once it’s finished installing;
  3. Open the application called Terminal (Command Prompt for Windows computers);
  4. Change to the correct directory by typing this and then hit enter:
    cd /Applications
  5. Then, copy and paste this command, followed by enter:
    sudo find Spotify.app -exec chmod 755 {} \;
  6. When prompted, enter your Mac user’s password and hit enter;
  7. Open the Spotify.app.

It is obviously if you open Terminal before installing Spotify.app you’ll get the ‘No such file or directory’ message.

Note: If all of this still doesn’t work, I found another temporary solution by simply dragging the Spotify.app from the Applications folder onto a USB and running Spotify from there. This is because by default Mac ignores ownership on USB volumes.
