Last updated on by pistouri

After the update W10 version 1903 (Windows 10 May 2019) the login screen appears blurry.

It is not possible to disable this feature from the section Settings → Personalization.

Solution 1 with Disable_acrylic_blur_effect_on_Sign-in_sceen_background file

Using a ready-made REG file:

Download / Save this file Disable_acrylic_blur_effect_on_Sign-in_sceen_background.reg

Double click on the file and authorize its execution

To blur the screen:


Double-click on the file and allow it to run

Note as a black screen 2 seconds before seeing the desktop, this has no consequence.

Solution 2 Change a registry key

Disable blurry background using registry keys

Touch Windows + R

Tape → regedit

Go to this registry key:


Right click in the right pane, create a new DWORD file (32 bits)

info: If Windows is in 64 bits create DWORD file (32 bits)

Name it → DisableAcrylicBackgroundOnLogon

In front of Value data:

To put 1 (in Hexadecimal).

Restart the computer for the changes to take effect.

Solution 3 With the Group Policy Editor

Using Group Policy (with Windows 10 Pro).

Touch Windows + R then type → gpedit.msc

In the Group Policy Editor, go to:

Computer Configuration Administrative Templates System Login.

Double click to open Show background settings for login.

The default is No configured.

To deactivate, select disabled

Click on OK and check the login screen.

If that doesn't work, restart your computer or check the next time you restart your computer.
