In today’s post we will share you world’s best theme to change default Windows 7 logon screen to look like OS X Mountain Lion. However the pack only works with Windows7 SP1 32bit and 64bit so don’t ever try it on Windows 8, XP or Vista except if you know how to tweak it yourself.

How to install login screen?
Once downloaded, extract the downloaded RAR file using 7-Zip or WinRAR. You’ll then see 2 folders: x64 (64-bit) Files and x86 (32-bit) Files
Windows 7 32-bit users will need to use files present in “x86 (32-bit) Files” folder and Windows 7 64-bit users will need to use files present in “x64 (64-bit) Files” folder.
Both folders contains following 2 files which are required to have OS X Mountain Lion look-like login screen in Windows 7: authui.dll and basebrd.dll.
“authui.dll” file is the main file which will provide new login screen in Windows 7. “basebrd.dll” file will only replace Windows 7 branding logo which is displayed in bottom-center of login screen with new OS X ML branding logo.
After extracting the downloaded file, go to “C:\Windows\System32″ folder and take ownership of authui.dll file. To take ownership, read our previous tutorial. We assume that you have installed Windows 7 in C: drive, if its installed in some other drive in your system, change C:\ to that drive letter.
Once you have taken ownership of the file, rename it to some other name like authui_bak.dll. Now copy new authui.dll file from the extracted folder to “C:\Windows\System32″ folder.
NOTE: 64-bit Windows users will also need to replace “authui.dll” file present in “C:\Windows\SysWOW64″ folder. Now go to “C:\Windows\Branding\Basebrd” folder and take ownership of basebrd.dll file.
Again, once you have taken ownership of the file, rename it to some other name like basebrd_bak.dll. Now copy new basebrd.dll file from the extracted folder to “C:\Windows\Branding\Basebrd” folder. At last set the “Background.jpg” file present in the downloaded archive as login screen background.
Enjoy your new Windows 7 login screen.
