Customizing the Look of the Startup

Windows XP has a great new look, but after a while, the new look can get old. With the help of some cool tools and tricks, you can change many parts of Windows XP.

   This post will guide you through customizing two parts of your computer, the boot screen and the Welcome/logon screen. You will see how to replace the boring boot screen with premade screes and even how to make some of your own.

Customizing the Windows Welcome Screen XP Boot Screen

     Every time I turn on my computer, I am forced to stare at the boring Windows XP boot screen. Although, I must admit, I found the moving blue bars very amusing at first, after a few months, I became bored and wanted something different. Although changing the boot screen is not a feature that the Windows XP team at Microsoft has built into Windows, doing so is still possible.

Changing the boot screen

     The image that is displayed during the boot is hidden away in a system file called ntoskrnl.exe. This system file is loaded during the system boot and is what displays the boot image and animation.

     When users first started to make their own boot screens, they would use resource hacking tools to hack into the file and replace the old Windows XP bitmap image file with one that they made. Then, they would swap the old system file with the hacked version of the system file so that the new boot screen would be displayed.
      The majority of users do not start off by making their own boot screen. Instead, they download one that someone else made from the Web. Unfortunately, the only way to distribute a boot screen is to share the system file that the author has hacked from his or her system. This method of distributing boot screens works for some people, but it may cause serious problems for the majority of users.

The problems of changing the boot screen

      If you download a hacked system file with a new boot screen and replace the old file on your computer, after you restart, you may find that your computer will not start and will give you a nice error message. “C:\Windows\System32\ntoskrnl.exe is missing or corrupt.” Missing or corrupt? Uh-oh. This is the most common problem that users experience when trying to change their boot screen using the file swap technique.

     Users that get this message, or any similar error message, are receiving it because they replaced their system file with a file that is not compatible with their version of Windows XP.

      Windows XP was released in many different languages for different parts of the world. Each language version of XP has a slightly different version of code. Additionally, Microsoft continuously releases software update patches to update the code of the system files such as the monthly security updates and almost yearly service packs. All of these factors result in several different versions of the boot screen system file floating around on the Web.

      You could find a boot screen file that was made from a hacked system file from the German version of Windows XP. Or more commonly, you could find a boot screen that was made from a hacked file from the original version of Windows XP. When you try to install that boot screen on a computer that, for example, has Service Pack 2 installed on the English version of XP, you will have problems.

      Windows XP will only work with a specific version of the system file that contains the boot screen. This arrangement complicates the change of the boot screen with the common file swap technique. It will do so because users will have difficulty telling on what version of Windows XP a particular boot screen that is distributed on the Web will work.

       Users have to be aware of more than just the version problem. Because you are downloading a hacked version of a critical system file that is executed during the boot sequence, you could possibly download a version that someone modified and in which he or she put some variation of malicious code that could harm your computer. Read the next section to find out how to change your boot screen safely.
