Tech Tip of the Week: How to Change the Logon Screen Wallpaper on Windows 7

Thanks! This really helped.

Great guide -- I have just one complaint. You have an image that seems to imply that the background image's name should be defaultBackground.jpg, but it doesn't work unless it's backgroundDefault.jpg. This tripped me up for about a minute before I reread the article.

I'm working on the bitmap gark with this. Just changed my PC's logon spash welcome screen via a quick take ownership of the files with this, then did a solid color with Windows paint, since that's my pref. It was fast, easy, didn't even have to change the registry value with the OEM installed. Now logon stays one color cept' for the boot screen deal, which am attacking next. Probably just a bitmap changeover internal same as I did the OEM & Windows/Microsoft files. Don't do this though unless you are familiar with internals to your PC very well, plus I over-wrote the files, and once it's done it's done. For me was a cut/dry issue but have worked with computers very long time, for others recommend backup, and known tweeks/tricks posted to net. Just another quirk way I knew, sort of a side door way to differ from known methods.

i need help, i used tweaks but now i can't use wifi sync with my iPhone because of the third party software, plus in the picture it displays defaultBackground.jpg, but in the description it says backgroundDefault.jpg, neither worked..

The manual instructions worked like a charm. Thank you!!!

Or you can do it manually... which is.. fun! it gives you something to kill time with while getting to know your computer a little better and understanding the complexity of this marvelous machine!!

Works great and sure is better that the boring default background. One problem I'v encounted is that when I enable a new background my windows logon and logoff sounds stop working until I change back to default. Any ideas why??

Only just found this method. Does it have to be a JPEG? And why does it have to be smaller than 248kb?

Just what I needed.
Thanks alot!

I changed mine manually now my graphics card is acting up.Is there a way to change it back to default? PLZ HELP

the map info already excist in my case. What should I do?
The map has 112 folders and 43 files.

The Info and background folder are already there and the background image I'm trying to replace will not let me. Says I need permission from TrustedInstaller???? Is there another way to change the windows logon screen?

This is really neat, but it seems there already is a folder there labeled "Info", so should I just have "info" overwrite it?

,,,I had the same intrusion/instruction from the O/S,,,

Also I noticed that there is another file in the at this address C:\Windows\SysWOW64\oobe\info\background.bmp, which matches the file used as the splash screen it's 2.25Mb. I tried to change permissions but was denied?

I even tried changing the file type to a .bmp instead of the .jpg with -NO- change in the Logon splash screen

The Microsoft page is as old as this original post/tip have they changed the permissions?
