How to change the hideous screen BEFORE logging in. The "Lock Screen" method only works if only ONE user account is set up, and not in a cooperate environment. Go to C:\ProgramData\Microsoft\Windows
Right click folder "SystemData", "Properties", take ownership, and give full access right to yourself AND SYSTEM. If you forget SYSTEM you may get a blank pre-login screen. Windows will correct the rights upon next reboot unless you forgot "SYSTEM".
Then go on to C:\ProgramData\Microsoft\Windows\SystemData\S-1-5-18\ReadOnly\LockScreen_Z
There are the "cached" backgound images. Right click each (usually only one), give yourself full access rights, and then delete it.
Then go to C:\Windows\Web\Screen
The img100.jpg is the one Windows 8.1 uses as template to create the background. Take ownership of the file, and rename it, I used the name img100x.jpg. I don't recommend deleting it.
Copy your own img100.jpg in there. It should be .jpg, 1920x1200.
Reboot.
Done.

Read this thread with the same topic about Windows 8, so many so called "Microsoft Professionals" don't get it what it is about: http://social.technet.microsoft.com/Forums/windows/en-US/82e7ae0f-1b6e-4d04-ae05-8278911af3e2/changing-the-prelogin-screen-background-picture?forum=w8itprogeneral

Other techincal notes: Yes, recorded with a camera, you cannot record the pre-logon screen and a reboot with fraps and the like.
