Hello,
- Log on to your Windows 10 computer using the account with which you want to change your desktop background.
- On the desktop, right-click anywhere.
- From the context menu, click Personalize.
- In the Personalization window, from the bottom of the right pane, click the Desktop Background option.
- In the Desktop Background window, check the check-box at the top-left corner of the image that you want to use as your desktop wallpaper.
Note: If you want, you can select more than one image to rotate automatically throughout the day. You can choose a time interval from the Change picture every drop-down list. You can also check the Shuffle check-box to have Windows 10 change your chosen desktop images in a random order.
- Once everything is configured, click Save changes, and close the Personalization window.
