Is it possible to remove the fade effect between login?

I'm basically asking this question:

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?

I'm asking again because the aforementioned question didn't have any useful answers, but an answer was accepted anyway. I would like to know if any new findings have been made since that question was asked two years ago.

For me, though, I have my login background the same as my desktop. When it fades out, it removes the coolness that I get.

Solution 1:

(Posting this as an answer so later visitors can see it better.)

Based on the comments above, it seems there's no way to remove the fade in on screen unlock. It seems that the fade-out/ fade in animation is actually covering for Windows doing something when it unlocks the screen (much like the black flash you get if you hit control-alt-delete between the normal desktop and the lock menu). If there was no animation, the lockscreen would probably not take any less time to enter or exit, it would instead appear to hang for anywhere from half a second to a couple of seconds (depending on your computer) on a black screen. That is, the animation itself isn't the source of the delay, it's an attempt by Windows to mask the delay.

Solution 2:

To avoid screen flicker when unnecessary animations turned off, I went to: Control Panel\Appearance and Personalization\Personalization and chose "Windows 7 basic".
