How to show a clear logon background on Windows 10

When you sign-in to a Windows 10 device you may notice a rather odd behavior. The background image is displayed just fine when you start the device but as soon as you interact with the screen, it is blurred. The following guide helps you restore a clear logon background.

Microsoft probably thought it a good idea to put the focus on the sign-in form and the few icons that it displays on the screen. The change was introduced in Windows 10 version 1903 and is active by default in all recent versions of Microsoft's operating system.

Windows 10 provides administrators with several options when it comes to disabling the lockscreen blur. The following guide walks you through all available options.

Option 1: Settings

This is probably the easiest option as it requires no changes to the Windows Registry or Group Policy.

  1. Open the Windows 10 Start Menu and select Settings, or use the keyboard shortcut Windows-I to open the Settings application directly.
  2. Go to Personalization > Colors
  3. Toggle the option "Transparency effects" so that its value is "Off".

Note that this turns off all transparency effects on the system.

Undo this by setting the value of Transparency effects to On.

Option 2: Group Policy

Microsoft added an option to the Group Policy that provides a narrower solution as it is designed to show a clear background.

Note that the Group Policy Editor is not part of Home versions of Windows 10.

  1. Use the keyboard shortcut Windows-R to open the run box.
  2. Type gpedit.msc and select OK to start the Group Policy Editor.
  3. Go to Computer Configuration > Administrative Templates > System > Logon.
  4. Double-click on "Show clear logon background".
  5. Change the status of the policy to "Enabled" and click ok.

The policy's description:

This policy setting disables the acrylic blur effect on logon background image.

If you enable this policy, the logon background image shows without blur.
If you disable or do not configure this policy, the logon background image adopts the acrylic blur effect.

Undo this by setting the policy to Disabled or Not Configured.

Option 3: The Windows Registry

You can also edit the Windows 10 Registry to force the system to display a clear background on the lockscreen. The option is useful to Home users as they cannot use the Group Policy to do that.

  1. Use the keyboard shortcut Windows-R to open the run box.
  2. Type regedit.exe and select OK to start the Registry Editor.
  3. Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System.
    1. If any of the keys do not exist, e.g. System, right-click on the previous key, e.g. Windows in the case of system and select New > Key to create it.
  4. Right-click on System and select New > Dword (32-bit) Value.
  5. Name it DisableAcrylicBackgroundOnLogon.
  6. Double-click on the newly created Dword and set its value to 1.
  7. Restart the computer.

Undo this by setting the value of the Dword DisableAcrylicBackgroundOnLogon to 0, or by deleting the Dword.

Closing Words

All three options work but you may favor the second and third options as they change the lockscreen behavior only while the first disables all transparency effects on the system.

Now You: What is your take on transparency effects in operating systems or applications?

    Images on logon screen are superfluous. I disabled the lockscreen (a PC needs no such feature, especially since it just duplicates the logonscreen) and my logonscreen inherits my system accent colour, so plain gray.

      @Yuliya: Your comments are nearly all superfluous, especially the ones that pertain to Mozilla, have you got any tips on how to disable them?

      Windows 10 is both a mystery and a mess.

      On one account on my computer, the login screen image refuses to be changed. I select another one and it still display the old one, I select another method – Slideshow – still shows the same static image.

      Windows 7 and XP weren’t like that – they “listened” when you tell them something, instead of attempting to know better than you what and how should be done.

    i dont see it as “odd behavior”. Feature is there because its idea is to focus user to login process.

      It’s “odd behavior”…because it wasn’t LIKE this before 1903…

      Some of us notice these things…you don’t have to notice it or care for it….great, that’s you…

    Lock screen on custom lockscreen under Microsoft Windows [Version 10.0.18363.959] Home – The lock screen is clear until I press the Space key to actually login. I like this design decision as it is.

    Good to know Martin. Nice little tweak for those who prefer this option. Those of us who don’t live in the land of angry rants and gray that is.

    the blur effect is consider a virus…and every time i ‘change’ the file…(USING) THE WAYS YOU said above…………..it still ‘revert’ back to the distorted screen…MS NEED TO ‘FIX’ THIS VIRUS…NOW
    I HATE IT—-they need to ‘FIX’ it so when you get to the log on screen…its ‘CLEAR’
    NO MATTER HOW MANY TIMES, I ‘USE THE INSTRUCTION’ ABOVE……’ THEY ‘NEVER STICK
    AND I FEEL I AM WAISTING TIME, WITH THE DISTORTED SCREEN

    I changed the registry as described, but have still the blur effect.
    With earlier w10 the effect was smaller (only a little blur), which was just nice.
    I accept it as it is (but for me it is ugly), i suppose windows is going down more and more…

    oops, checked again and really I wrote Acryl instead of Acrylic.
    Maybe I’m also going down more and more…
