SYMPTOMS
When you try to install Windows XP Service Pack 1 (SP1),
you may receive the following error message:

Windows has detected that one or more protected core
system files (kernel) on your computer have been modified.
The Service Pack contains updated versions of those files,
which work to provide a stable environment for your
programs. Due to this modification, the Service Pack will
not be installed. For more information, see Knowledge Base
article Q327101 at http://support.microsoft.com.
CAUSE
This behavior may occur if your computer has a modified
version of the Ntoskrnl.exe file that uses the /KERNEL
switch in the Boot.ini file. This condition may exist
because your computer has a third-party program installed
that customizes the graphics that are displayed when your
computer starts up. Third-party programs that can cause
this condition include the following:
BootXP
LogonUI Boot Randomizer
RESOLUTION
To resolve this problem, follow these steps:
Click OK to close the error message.
Click Start, click Run, and then type appwiz.cpl in the
Open box.
Click the program that customizes the startup graphics,
and then click Remove.
Restart your computer, and then try to install SP1 again.
If the problem persists, go to step 5.
On the desktop, right-click My Computer, and then click
Properties.
Click the Advanced tab, and then click Settings under
Startup and Recovery.
Under System Startup, click Edit.

The Boot.ini file opens in Notepad.
Locate and then delete the /KERNEL= switch.
Save and then close the Boot.ini file.
Restart your computer.
Try to install Windows XP SP1.
NOTE: After you complete the steps to resolve the problem,
SP1 should install correctly. However, if your computer is
running a modified Ntoskrnl.exe file, you may receive a
message when you try to install SP1 that states that the
SP1 setup program will replace the modified Ntoskrnl.exe
file with an updated version.
STATUS
This behavior is by design.
