As of the Windows update of May 10, 2019, the login screen uses the “Fluid Design” blurred transparency that is in the taskbar, the Start menu and elsewhere. If you want to clearly see the background of the lock screen, here we show you how to disable blur.
If you disable the lock screen, Windows 10 jumps directly to the login screen, avoiding it. With the recent update, the background image has been distorted beyond recognition due to the "Acrylic" style transparency effect used throughout Windows. Depending on the version of Windows 10 you have, these methods will return clarity to your background.
The easy way: disable transparency throughout the system
If you don't like the aspect of the transparency effect, you can easily disable it for all aspects of Windows 10. This will disable it not only on the lock screen, but also on the taskbar and even applications such as Calculator. This method is an all-or-nothing approach and should only be disabled if you don't enjoy the appearance anywhere on your desktop.
First, open the Settings application and go to Settings and then Personalization. Or right-click on an empty space on the Desktop and then click on "Customize."
Select «Colors» on the left side of the Settings window, scroll down until you see the option labeled «Transparency effects». Then, set it to "Disabled."
To undo this change and enable the transparency effect in Windows 10, you can go back here and toggle this function to «On».
Home users: disable background blur through the Windows 10 registry
If you have Windows 10 Home, you will have to edit the Windows Registry to make these changes. You can also do it this way if you have Windows 10 Professional or Enterprise, but you feel more comfortable working in the Registry than in the Group Policy Editor.
However, if you have Pro or Enterprise, we recommend using the simplest Group Policy Editor.
We warn you something: Registry Editor is a powerful tool and its misuse can make your system unstable or even inoperable. This is a fairly simple trick, as long as you follow the instructions, you shouldn't have any problems.
That said, if you've never worked with him before, consider reading as much as possible about the Registry Editor before starting. Definitely make a backup copy of the Registry and your computer, before making changes.
Also, you must make a system restore point before continuing. It is never a bad idea and it could not hurt to do it manually; That way, if something goes wrong, you can always go back.
Then, open the Registry Editor by pressing Windows + R on your keyboard. Now type "regedit" in the box and press Enter.
Navigate to the following key in the left sidebar, or paste it directly into the address bar at the top:
Right-click on the Windows key, select New and then click Password. Then name it "System" and press Enter.
Right-click on the System key, select New and then select DWORD Value (32 bits), then call it "DisableAcrylicBackgroundOnLogon".
Double-click on the DWORD you create and then change the Value data from «0» to «1».
You should not have to restart your computer for this change to take effect. Simply press Windows + L to lock your computer and you will see the login screen with the background image in full focus, with no blur added.
To undo this change, you can return to regedit, locate the value "DisableAcrylicBackgroundOnLogon", delete it or set it to "0".
Professional and business users: disable background blur using group policy
If you use Windows 10 Professional or Enterprise, the easiest way to disable background blur is by using the Local Group Policy Editor. It is a fairly powerful tool, so if you have never used it before, it is worth taking some time to learn what you can do.
Also, if you are in a company's network, do everyone a favor and check first with your administrator. If your work computer is part of a domain, you are also likely to be part of a domain group policy that will replace the local group policy anyway.
You must also make a system restore point before continuing. It is never a bad idea to play and if something goes wrong, you can always restore your system as it was before.
First, start the group policy editor by pressing Windows + R, type "gpedit.msc" in the box and press Enter.
Go to Computer Configuration, then Administrative Templates. Then, go to System and Login.
Search for «Show clear login background» in the right panel and double click on it.
Now set "Show clear login background" to "On" and then click "OK." You must restart your computer for the changes to take effect.
If you have the lock screen disabled before enabling this setting in the Group Policy Editor. For some reason, Windows will reset it to the default settings, again. All you have to do to skip the lock screen is to add the registry value again.
To revert this setting to the default, go back to the previous point, double-click on "Show clear login background" and click on "Disabled" or "Not configured".
