Change Your traditional startup and Logoff screens

To change your start up screen:

First Create a 320x400 bitmap in the root directory 
Now give it a name as LOGO.SYS
From now your startup screen will be changed to the given image or your selected image!

To change your logoff screen:

In the Windows directory there are two files named LOGOW.SYS and LOGOS.SYS. In which LOGOW.SYS is the "Wait while Shutting down …" screen. Where as LOGOS.SYS is the "You may now shut-off or Reboot screen".
Now here what you have to do is to make two files in a paint brush and just name it as LOGOW.SYS and LOGOS.SYS. Than you have to replace this files with an actual windows file.
That’s it!
Here it should be noticed that these both files should have same size. Other wise undesired result will come! But its not a major matter. Enjoy!
