How can I change lock screen background windows 10 by my picture each time I login or each day? Although I like Bing?s picture but I also want to use my picture.
Settings > Personalization > Lock screen
You can choose a Background here. Windows spotlight will show images that Microsoft has chosen. Picture and Slideshow let you choose your own picture(s).
You can also open a photo in the Photos app, click the three dots in the top right, Set as, and then Set as lock screen.
