Is customizing the login screen possible?

Hi,

I know you can modify the lockscreen's background image, but what I would be interested in is using my desktop wallpaper as the background of the login screen (where I input my password), right after the lockscreen.

I haven't found anything about it, am I the only person interested in doing that?

Thanks for any reply

Edited because uncle Tom didn't read the question properly.
Not sure about changing the logon screen image, but changing the colour is easy enough.

The settings are stored at

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Accent

Create a DWORD value named "StartColor" and set this to the hex value of your preferred colour
Create a DWORD value named "AccentColor" and set this to the hex value of your preferred colour

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Accent

Create a DWORD value named "DefaultStartColor" and set this to the hex value of your preferred colour

Hope this helps
