Changing the Logon Background Color

If you want to change the green logon color:

1. Start Regedit
2. Go to HKEY_USERS\.DEFAULT\Control Panel\Colors\Background
3. Change the three numbers from the default of 58 110 165 to the RGB values you want
4. For example 110 110 255 is a fairly light blue, 0 0 0 would be black
5. Log off and log back on again to see the change.
