According to new references spotted in the fresh preview
builds, Microsoft is now internally testing minor improvements
for the Windows 10 lock screen, desktop, and the camera
The improvements are accessible in Windows 10 Build 21277 or
newer but they’re hidden behind experimental flags.
The Windows lock screen experience was first introduced with
Windows 8 and it’s getting better in the next release of
Windows 10 with support for Parallax 3D effect. If it works as
expected on your Windows tablet, it would make your lock screen
look cooler when you rotate your device and accelerometer is
If you don’t like the Parallax feature, you’ll be able to turn
off the ‘subtle paning effect driven by the device’s
accelerometer’ in the Settings app, as shown in the screenshot
When this option is turned off, users will see static lock
screen background image instead.
Spotlight for desktop
As we reported in October, Microsoft has been trying to bring
the Windows Spotlight feature to the desktop. It looks like the
feature is now set to arrive in the second half of 2021 with
Windows 10 21H2 (also known as Sun Valley update).
Spotlight will allow you to replace your desktop background
with Bing’s Image of the day. To enable this feature on
desktop, you would need to open Settings > Personalization
and then choose Spotlight Collection from the options, as shown
in the screenshot below.
Microsoft also appears to be experimenting with new Camera
settings inside the main Settings app of Windows 10.
The new camera settings will allow you to change the
brightness, contrast, preview the image quality, address
hardware issues, and more directly from the Settings app.
In addition to lock screen and desktop features,
this preview build also comes with improvements to the
taskbar, battery monitor as well as the built-in settings
