Windows 10 often gives users a login screen with beautiful, ever-changing photography from around the world. But after recent updates, many are complaining that the pretty pictures are suddenly blurry.
This is a feature, not a bug, that you can defeat. But it’s a little tricky to find what to change:
Click Start, then Settings.
Click Personalizations, then Colors.
Turn “Transparency Effects” off.
The next time you encounter your login/lock screen, the Windows Spotlight photo should be crisp again!
