Windows Update Error 0x80240017

What is WU-0x80240017?

The update is not applicable to the operating system. This usually happens when the update package architecture does not match your system (e.g. 64-bit update on 32-bit OS) or prerequisite updates are missing.

Common Causes

• Mismatch between the update package architecture (x86/x64) and the installed Windows version.
• Missing Servicing Stack Updates (SSU) that are prerequisites for the current cumulative update.
• Attempting to install an update meant for a different version of Windows OS.

Step-by-Step Fix Guide

• 1
  Verify your system architecture (32-bit or 64-bit) in system settings.
• 2
  Manually download the correct update package directly from the Microsoft Update Catalog.
• 3
  Install the latest official Servicing Stack Update (SSU) before applying cumulative patches.
