Windows XP Service Pack 3 Setup Error

I'm trying to upgrade WINDOWS XP to service pack 3 but I got the error window

"The file c:\windows\system32\ntoskrnl.exe is open or in use by anotherapplication. Please close all other application and click Retry."

So I closed all of the programs I was using but it's still error.

Could you please help me fix this problem I really want to install pack3.

Thank you

Make certain that your disk drive has the space required, at least 2GB for a PC that is fully loaded with applications. This 2GB does not include the recommended 15% free disk space requirement for Windows XP.

Install SP3 in 'Clean Boot' mode:
How to configure Windows XP to start in a "clean boot" state
See the section titled: Manual steps to perform a clean boot in Windows XP, skipping step 4.

Why clean boot:
A “Clean Boot” insures that only a minimal set of Windows Services and applications are running. This means your Anti Virus software, third party Firewall and other background applications will not be running; thereby reducing the chances that installing SP3 will fail. Just remember to undo the “Clean Boot” changes after installing SP3.

Do not use the Windows Update web site, if at all possible download the service pack installation file directly to your hard drive and install SP3 using the file you downloaded.

Where to download the SP3 installation file:
(File is large but will only install components that your PC requires)
