Windows XP reformat Error Code 0x8024400A

Recently I decided to bring my old Dell laptop back to factory Windows XP. I’ve been moving more towards using my PC and wanted something to do testing on. After I used my Dell install CDs I found that no matter what I tried I could not update the computer. It kept throwing the error Error Code 0x8024400A.

After trying various different things I eventually found this post on the Microsoft forum that said the Windows Update Program (WUP) isn’t compatibile with pre SP3 or does not have permission to do as much. So he posted some direct links to download the update WUP tool so that you can install it manually.
