How to Fix Windows Error Code 0x8024400A: Windows Update

Hello everyone, today I will be talking about how to fix the error code 0x8024400A. Now this blog post ties in with my last one (How to Factory Reset Your Laptop) because after I had factory reset my laptop I had to update Windows XP. However, when I tried to update my laptop I got this error code: 0x8024400A. What followed was a series of Google search’s to try and find to fix to this problem.

What the problem turn's out to be is that WUP (the program used to update Windows) is out of date and the way you usually update it is through Windows Updater. So it's a nasty loop that you have to get out of. Luckily, you can update WUP via the Microsoft website. Follow the links below to download the updated WUP:

(32 bit) X86 - http://download.windowsupdate.com/windowsupdate/redist/standalone/7.4.76...
(64 bit) X64 - http://download.windowsupdate.com/windowsupdate/redist/standalone/7.4.76...

Once you've downloaded the file and installed it, restart your PC and try and update Windows XP again and it should work.
