A. You can set a custom background for the logon screen in the release candidate and release to manufacturing versions of Windows 7, as shown here.

Click to expand.

To set a custom picture, place a JPG named backgroundDefault.jpg in the %windir%\system32\oobe\info\backgrounds folder. Now go to the registry and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background. There should be a DWORD value named OEMBackground (create it if it's missing). Set the value to 1 and click OK.

Now when you log off or switch users the new background picture will be displayed. No reboot is necessary.

You can also place custom files in the backgrounds folder with the name background<resolution> to have different pictures for different resolutions. For example, a 1024×768 resolution picture should be save as background1024x768.jpg.
