How do I disable the fade out/fade in effect when unlocking a Windows 7 workstation?

Question

Is it possible to remove the fade effect between login?

When I press Win+L, the “Locked” screen (with the password prompt) appears immediately. That’s nice, but not terribly important: I’m probably leaving the computer anyway.

But after I type the password (to unlock the workstation), the desktop doesn’t appear immediately: instead, the “Locked” screen slowly fades out, the desktop slowly fades in, wasting my time, and all keys (e.g. Win+R) pressed during this interval are completely swallowed, forcing me to wait unnecessarily. This is extremely annoying because when I unlock the workstation, I generally want to use my computer.

How do I disable this fade out/fade in effect and have the desktop appear immediately, in the same way that the “Locked” screen appears immediately?

Solution

It does not appear to be possible to turn this effect off.

You can poke around HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion‌​\Authentication\Logo‌​nUI but it doesn't have anything for fade. I have disabled visual effects and it still fades, so I guess this may be something you will have to live with.

Takes about 1 second for me... eases me gently back into my work :¬)

The effect does not function on my VirtualBox installation of Windows 7 Ultimate. This indicates a possibility of disabling the effect, but I don't know how.

@Deltik doesn't function on my laptop when using the XP graphics card driver. Using the W7 driver makes it functions, but it has other bugs.
