Someone asked me about this today so I thought I would share...
Hello this is a short tutorial on how to change your boot screen and your login screen
Logins
1.Backup (copy) the file %windir%\system32\logonui.exe (most likely C:\windows\system32\logonui.exe - the logon)
2.Create and extract logonui.exe to a directory other than %windir%\system32 (most likely C:\windows\system32)
3.Reboot your computer into Safe Mode (hit F8 before the boot screen) or into true DOS (from a boot disk)
4.Overwrite the file %windir%\system32\logonui.exe (which should have been backed up) with the extracted exe
5.Reboot your computer as you normally would
Boot screen
1.Backup (copy) the file %windir%\system32\ntoskrnl.exe (most likely C:\windows\system32\ntoskrnl.exe - the boot screen)
