Disabling the Windows 10 Blurred Sign-on Screen

Written by Eric Wyatt (last updated July 15, 2019)


Recently, when Microsoft updated Windows 10, they included a new User Interface (UI) feature which blurs the background image of the sign-in screen. Some users enjoy this feature, while others prefer the previous, non-blurred version. One person who doesn't like this UI feature is Miguel. Miguel feels the new UI isn't as colorful and he doesn't want to uninstall the current operating system. If you prefer to not have the blurred background on the sign-in screen, follow these simple steps:

  1. Press Windows+R. Windows opens the Run window.
  2. Type "regedit" (without quotes) and press Enter. Windows opens the Registry Editor.
  3. In the left-side panel, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System.
  4. Right click any blank area within the right-side panel of the Regedit window and select "New" from the resulting Context menu. From the fly-out menu choose DWORD (32-bit) Value.
  5. Set the name of the new DWORD (32-bit) Value to "DisableAcrylicBackgroundOnLogin" (without quotes) and press Enter. Windows creates a new DWORD with the DisableAcrylicBackgroundOnLogin name.
  6. In the right-side panel, double-click the newly added item. This brings up the Edit DWORD (32-bit) Value dialog box. (See Figure 1.)
  7. Figure 1. The Edit DWORD (32-bit) Value dialog box.

  8. In the Value data field change the "0" to a "1" (without quotes).
  9. Click on OK to close the dialog box.
  10. Close the Registry Editor app. The change should take effect the next time your computer is locked.

To turn blurring back on, repeat the steps above, and at step 7 change the "1" back to a "0" the change will take effect as it did before.

Now you can turn off the blurring effect, and if you're like Miguel, you can enjoy the photo you have chosen as your background image when you sign-in to your computer.

Hi, Miguel
I'm glad it works for you too. Really, I cannot answer your question for sure because I am not a computer geek. In my opinion, since "DisableAcrylicBackgroundOnLogin" in QWord(64-bit) remains inactive, ie seems useless, just delete it and see what happens, or, better, export it (go to file and click on 'export') somewhere, eg. your Documents, and import it again, by right clicking it, in case you find out that something in your computer does not function as expected.
Have a nice day

Hi, Spyros: Thank you very much for your Tip. In fact, disabling 'transparency effects' returns colorful images when starting Windows 10, latest version. On the other hand, "DisableAcrylicBackgroundOnLogin" in QWord(64-bit) field with value 1, added previously, is still in the Windows Registry: Is it necessary or must be deleted? Seems doesn't take any effect...

As always, thanks again.

There is another way to turn off the blurring effect, if you are not familiar with tweaking the registry. Right click on your desktop and choose 'personalize'. Click on 'colors', on the left pane, scroll down and switch off 'transparency effects', on the right pane. That's it, it works fine for me.

Hi Eric, how are you? Fine? I hope so...

Thank you very much for your kind answer through this Windows 10 tip. Well, I followed your instructions, but when selecting DWORD (32-bit) Value, no editing tasks were possible in this 'field'; editing tasks weren't enabled if DWORD (32-bit) Value is selected. So, due to my OS System is Windows 10 Home Edition 64 Bits, version 1903 18362.239, I selected QWORD (64-bit) Value instead, renamed to "DisableAcrylicBackgroundOnLogin" (without quotes) and press Enter. After that, I double-clicked the new "DisableAcrylicBackgroundOnLogin" (without quotes) just created and changed 0 to 1 in the Value data field. Finally, I Closed the Registry Editor app. However, when restarting PC system, blurred image is still displayed again... ¡Nothing changed!

In any case, thanks again, Eric, for your attention.
