How to Enable or Disable Acrylic Blur Effect on Sign-in Screen Background in Windows 10


Starting with Windows 10 build 18237, Microsoft added an acrylic blur effect to the sign-in screen background. The translucent texture of this transient surface helps you focus on the sign-in task by moving the actionable controls up in the visual hierarchy while maintaining their accessibility.

Starting with transparency effects that would also turn on or off the acrylic blur effect on their sign-in screen background.

Starting with Windows 10 build 18312, Microsoft added a new group policy setting allowing you (administrator) to enable or disable the acrylic blur effect feature on the sign-in screen background for all users without affecting their transparency effects setting.

If you enable the acrylic blur effect on the sign-in screen background, users will still have to turn on transparency effects for their account to see it.




This tutorial will show you how to enable or disable the acrylic blur effect on the sign-in screen background for all users in Windows 10.

You must be signed in as an administrator to enable or disable the acrylic blur effect on the sign-in screen background.

How to disable Sign-in screen acrylic (blur) background on Windows 10 May 2019 Update | Windows Central
- that's what you're referring to, I believe- the background to the login screen, rather than the lock screen- but should not affect the ability to log on.

That said, if tahalodhi16 is having trouble logging on, but not otherwise, it's worth trying what you suggest.
The article I've quoted also gives the registry details, so that could be done in Safe Mode if it's easy to access that in this situation.

Clarification is needed else we are simply guessing.
