Bing4Free

Bing4Free is a small software application whose purpose is to help you download wallpapers from Bing. It can be deployed on all Windows flavors out there.
In order to run the program correctly on your system and avoid bumping into compatibility issues, you need to install Microsoft .NET Framework.

Comes in a portable edition

This is a portable utility which can be stored on USB flash drives or other devices to have it with you all the time. In addition, you may run it without administrative privileges. Gaining access to its features requires only opening the executable file because there’s no setup included in the process.

Intuitive interface

Bing4Free sports a clean and straightforward design which allows you to set up the dedicated parameters on the go. Although it does not offer support for a help manual, you can venture into tweaking the settings on your own because they look easy to work with.

Wallpaper downloading options

Bing4Free gives you the possibility to check out the downloaded images directly in the main window with the aid of thumbnails. In addition, you can set the selected picture as your current wallpaper.
What’s more, you are allowed to choose the folder where the wallpapers are stored, automatically look for new wallpapers at a predefined time interval (e.g. 1 minute, 10 minutes, 1 hour, 6 hours), automatically change the wallpaper at a certain time interval (from 1 minute up to 12 hours) using the latest set of images, as well as set the desktop background style (stretched, centered, tiled).
Other important options worth being mentioned enable you to run the application at Windows startup and configure proxy parameters. On the downside, the tool has not been updated for a long time so you may come across compatibility issues on newer operating systems like Windows 8 or 10.

Conclusion

To sum it up, Bing4Free can be used as wallpaper downloader and changer, and can be configured by rookies and professionals alike.
