Setting a Custom Desktop Background

Method 2:
To use a desktop background other than the default image shown in Figure 16-7 (or one provided by the manufacturer of your computer), follow these steps:

In the Start menu search box, type regedit and press Enter to open Registry Editor.

In Registry Editor, navigate to the HKLM\Software\Microsoft\Windows\ CurrentVersion\Authentication\LogonUI\Background key.

If a DWORD value named OEMBackground does not exist, create one. Set this value's data to 1.

In Windows Explorer, navigate to %Windir%\System32\Oobe\Info\Backgrounds. (If the subfolders of Oobe do not exist, create them.)

Copy the image you want to this folder, using these guidelines:

The image must be in jpg format, and the file size cannot exceed 256 KB.

Scale the image to the pixel dimensions of your primary monitor's native (or default) resolution, and name the file Backgroundwwwxhhh.jpg, where www and hhh represent the width and height, in pixels (for example, Background1600x1200.jpg).

Because this feature doesn't support all screen resolutions, create a copy of the image file and name it BackgroundDefault.jpg. If Windows is unable to use the resolution-specific image, it uses this one and stretches it to fit.

If that procedure sounds too daunting, download the Tweaks.com Logon Changer, a utility that compresses your image file (to stay under the file-size limit) as well as safely diving into the registry and deeply nested folders for you. Get it from w7io.com/1603.
