In a previous post, we discussed the Windows upgrade error 0x800700B7 0x2000a; however, this article will focus on another system error known as the Windows upgrade error 0x8007042B 0x4000D. This error occurs while trying to upgrade your system to a new version and can be caused by various factors.

Regardless of the cause of the problem, the solutions outlined in this guide will help you fix this error and get your system running without any trouble.

1. Remove pending .XML file

Windows Update generates the pending.xml file temporarily while performing an upgrade. It includes details on the files that require updating and the modifications that must be made to the system. However, if the files are corrupt or damaged, it can prevent Windows Update from running properly and result in the error.

Removing the pending.xml file will make Windows Update regenerate the file and restart the upgrade process, which will help resolve the error code 0x8007042B 0x4000D.

  1. Press Windows + R to open the Run dialogue, type cmd in the text field, then hold Ctrl + Shift + Enter to open the command prompt as administrator.
