This post is for the people who have not activated their Windows license yet.
Windows will not allow us to personalize the screens without activating the genuine license. Hence many of us will have default windows wallpaper and screensaver.
However we have third party apps to change the custom wallpaper and screen saver without activating the windows license. The application is free of cost and available in the Microsoft store itself.
The URL to download the Wallpaper Changer app is mentioned below,
Once the application is installed you can surf for online wallpapers and also create a collection of custom photos and make them as a screen saver or wallpaper.
Also you can set for daily Bing wallpaper change, randomly wallpaper and screen savers will be downloaded and changed from online.
