Windows Photo Viewer is one of the things that gets removed or hidden from access after upgrading to Windows 10. The new Photos app takes charge as the default handler for image files in Windows 10 and Windows 11.

The good news is Windows Photo Viewer application still exists in the same location in Windows 10 and Windows 11. But what is removed is only its registration.

Windows Photo Viewer is a lightweight app similar to the Office Picture Manager and Windows Live Photo Gallery, both of which are discontinued by Microsoft. But, Windows Photo Viewer remains an integral part of Windows 10/11.

Windows Photo Viewer is powered by a single DLL file named photoviewer.dll located in the C:\Program Files\Windows Photo Viewer directory in Windows 11 and earlier OS.

For example, this command-line will open a file named D:\sample.png using Windows Photo Viewer:

rundll32.exe "%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll", ImageView_Fullscreen d:\sample.png

Now, all we need to do is add Windows Photo Viewer file association settings to the registry. If you’re not a fan of the new Photos app, you can restore the missing Windows Photo Viewer registration in Windows 10 and 11.

Windows 10 Command Prompt Can Be Closed using ALT+F4 Hotkey

The much useful ALT+F4 key sequence closes any application, but not the Command Prompt window. Users had to type exit or click the Close button to close the window. This is the case in earlier versions of Windows (up to Windows 8.1), but have you noticed that the Windows 10 Command Prompt duly responds to ALT+F4 hotkey?

Not only that! You can even change the Windows 10 Command Prompt behavior as in earlier Windows versions. Probably the developers at Microsoft had legacy applications in mind. By the way, to make Command Prompt not respond to ALT+F4 key sequence, all you need to do is to edit a registry value.

How to Enable Balloon Tips (XP Style) in Windows 10

In Windows 10, application and system notifications are shown as toasts, instead of the balloon-tip style notification we’ve seen since Windows 2000/XP. Toast notifications disappear quickly whereas the balloon tip notifications appear on the screen as long as we have the mouse pointer hovering over the balloon. For some users, the balloon style notification suits well. Fortunately the Windows XP-style balloon tips can be activated in Windows 10 using a registry edit or via Group Policy.
