First Goto run and type Regedit and then Enter.

Then Goto the Key

Hkey_local_machinesoftwareMicrosoftwindowscurrentVersionAuthenticationlogonUIBackground.

Its data, of Boolean type, defines whether or not this behavior is turned on, i.e. 1 for enabled, 0 for disabled. This value may not exist by default, depending on your system. If its not there. Just create it. And give the value 1.

Agin goto Run and type %windir%system32oobeinfobackgrounds then enter. If the folder is not there just create it as the path I have given.

The following files (sorted by width-to-height ratio) are supported in this folder:

• backgroundDefault.jpg
• background768×1280.jpg  (0.6)
• background900×1440.jpg  (0.625)
• background960×1280.jpg  (0.75)
• background1024×1280.jpg (0.8)
• background1280×1024.jpg (1.25)
• background1024×768.jpg  (1.33-)
• background1280×960.jpg  (1.33-)
• background1600×1200.jpg (1.33-)
• background1440×900.jpg  (1.6)
• background1920×1200.jpg (1.6)
• background1280×768.jpg  (1.66-)
• background1360×768.jpg  (1.770833-)

NOTE: Images must be less than 256kb in size.

So copy anyof your favorite wallpaper and put it this folder with name backgroundDefault.jpg

The backgroundDefault.jpg image is loaded and stretched-to-fit when a resolution/ratio-specific background cannot be found. The other resolution/ratio-specific files are self-explanatory. If the background cannot be loaded (e.g. image physically too large, incorrect ratio, etc.), the default SKU-based image is loaded from imagesres.dll. You’ll see a Windows Server-themed grayish background in there, too, suggesting this functionality is not specific to client SKUs.
