  1. This worked for build 7057, but it doesn’t seem to work in build 7068. Can anyone confirm this?

  2. Just tried it on 7100.
    Step 4 is not needed.
    Step 6: the files with the resolution in the name do not work (background1600×1200.jpg for ex) .

  3. Cool. Do you know of a way to change the size of the user picture on this screen? It’s decent size when you have only one user but with two users they get really small. Maybe another handy utility?

  4. Yes. This works on X64 also.
    Just copy the file to C:WindowsSystem32OOBEINFOBackgrounds and make the registry change.
    (No need to copy it to the SYSWOW64 folder)

  5. in regedit, where the key should be:
    – right click
    – click “New…”
    – click “DWORD (32-bit) Value”
    – call it “OEMBackground”
    – set it’s value to be 1

    That should work…

  6. i tried it on windows 7 ultimate and it did not change anything. i followed all steps except for the size of the pic which is more than 256kb. anyone who knows why it does not change?

  7. Thanks for making the steps to changing the logon screen wallpaper so easy! In addition to adding personal touches to the background, I wanted to let you know that you can also change the logon box with just a few tweaks. The steps are pretty easy and users are able to get a sleek, modern logon box that didn’t originally make it to the final Windows Vista product. You can find more info on how to do it here:

  8. what about multiple pics in the background? If i have selected 10 pictures for desktop background, and through settings the background image changes after every 5 minutes, can i get this setting also when i lock my win 7?

  9. With some minor troubelshooting, I found that this was not working for me because I had the file titled “backgroundDefault.jpg” even though it was listed as a jpeg. I had to take off the .jpg to change the name to “backgroundDefault” and it worked.
    Thank you for publishing this article!

  10. you have to enable “Always use custom logon background” in GPO
    open up gpedit.msc go to computer configurationAdministrative TemplatesSystemlogon
