Make a Custom Logon Screen in Windows 7


Introduction: Make a Custom Logon Screen in Windows 7

About: I am an engineering student in the midwest. in my spare time, which become increasingly non-existent, I enjoy cooking, fixing things of mine, and wasting time on this website of course!

In previous versions of Windows, you could use third-party hacking applications to customize the logon background. In Windows 7 there is a manual, no hacking progam necessary, way to do it.

Step 1: Edit the Registry

Open the registry editor (search/run regedit). Go to the directory: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\
LoginUI\Background . Open the DWORD value OEMBackground. Change its value to 1.

Step 2: Make the Directory

Open C:\Windows\System32\oobe in Windows Explorer. In that location make a folder titled info. In info make a folder titled backgrounds. Most computers will not already have these two folders.

Step 3: Find a Picture

Try to find a picture that is similar resolution to a desktop background or your screen because it will be stretched to fit the screen. Also, the picture must be under 256KB file size to work.

Once you have the picture you want, copy it to the directory C:\Windows\System32\oobe\info\backgrounds . Change its name backgroundDefault.jpg . Logoff or restart your computer to test it.

    This feature is built into windows 10. Settings->Personalization->Lock Screen

    Then, select a photo


    Where can I get the background you have showing in the screenshot of step 3?

    Hey I did all you said but when i log in its still the same Win7 pic, I m using 32x Bit, is that ok?

    rename it " backgroundDefault" nothing else ^_^ thanks gamerguy!

    Just going to throw it out there... but... are your extensions hidden? If so then you're absolutely right. Adding the ".JPG" to the name on a system where extensions are hidden (which are set to be hidden by default in my experience) will name the file "backgroundDefault.jpg.jpg" on the system, even though you will see it as "backgroundDefault.jpg"

    Hmm.. cool and all but how do I change the loading screen image? Surely there is a way to do that...


    Works like a charm, thanks

    I can't find background under logonUI. sigh.

    I performed everything that you stated and did not have any effect. Is there no step to change the pathway that the OS uses for the background from the original BMP to the new JPG?

    Sorry you cannot change the pathway that the computer uses. Make sure that the folder titles are exactly the same as what I said and that the picture you are trying to use is a jpeg under 256KB.

    Well, the jpeg is barely under that. I'll try lowering it and see where that gets me.

    Open the start menu and use the search to find "regedit" The program should be first on the list. If not, you may not be using an administrative account since you need authorization to use it.

    Oh, well, that's what i tried last time. But, it worked this time. Thank you!
