Microsoft pushed a new Release Preview build for Windows Insiders. One of its hidden features is the new Lock Screen widgets, which were spotted earlier in one of the recent Windows 10 updates.

Windows 11's lock screen will soon support customizing which widgets appear. The change entered testing with Windows Insiders recently with the release of Windows 11 Build 22635.4870.

If you've recently updated your Windows 11 PC, you might be surprised to see three new widget boxes at the bottom of your lock screen, where there used to be nothing.
