How to unblur the (user account) password entry page image in Windows 10?

Solution 1:

You can install Winaero Tweaker https://winaero.com/winaero-tweaker it has a feature where you can disable the blur on the logon page.

Solution 2:

You can do that by changes in the registry:

Open in regedit the registry path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

Create a value of type DWORD-Value (32-Bit) and name it DisableAcrylicBackgroundOnLogon and set the value to 1.

After a reboot the aero glass effect (the blur effect) should be gone.
