Change Windows Logon background
Because I'm using the clasic theme with the clasic color scheme with a black background, that damn blue is annoying.
Click Start, Run and type REGEDIT and press Enter
Navigate to the following key:
In the right pane, double-click Background
In the Edit String dialog box, type the Color code in R G B format and then click OK.
Example: Type 0 0 0 if you want to see a Black background. You can choose any combination from 0-255
