What Are Windows Update Installation Failures?

Windows update installation failures occur when your computer is unable to successfully download or install updates provided by Microsoft. These updates are designed to enhance the functionality of your operating system, fix bugs, and patch security vulnerabilities.

Recognizing the signs of update installation failures can help you diagnose and address the issue promptly. Here are some common indicators:

  • Error Messages: One of the most obvious signs of a failed update is the appearance of error messages. These messages often include error codes that can help you identify the specific problem.
  • Stuck Updates: Sometimes, the update process may get stuck at a certain percentage, with no progress for an extended period.
  • System Instability: A failed update can cause your system to become unstable, leading to frequent crashes, slow performance, and unresponsive applications.
  • Repeated Update Attempts: If your computer repeatedly tries to install the same update without success, it’s a clear sign that something is wrong.
  • Missing Features: If certain features or functionalities that should have been included in the update are missing, it indicates that the update did not install correctly.

Common Causes of Windows Update Installation Failures

1. Lack of Disk Space

One of the most common reasons for update failures is insufficient disk space. Windows updates often require a significant amount of free space to download and install. If your hard drive is nearly full, the update may fail.

2. Corrupted Update Files

Occasionally, the files downloaded for the update may become corrupted. This can happen due to interrupted downloads, issues with the storage media, or problems during the file extraction process.

3. Conflicting Software or Drivers

Incompatibilities between the update and existing software or drivers on your computer can cause installation failures. For example, outdated drivers or security software may block the update process.

4. Internet Connectivity Issues

A stable internet connection is crucial for downloading updates. Network interruptions or slow internet speeds can result in incomplete downloads, leading to update failures.

5. Outdated System Files or Settings

Older system files or settings that have not been updated for a long time may be incompatible with the latest updates. This can cause conflicts during the installation process.

Specific Error Codes and Their Meanings

Windows update installation failures often come with specific error codes that provide clues about the underlying issue. Here are some common error codes and what they indicate:

Error Code and Meaning

0x80070020 – Another process is interfering with Windows Update.

0x80073712 – A file needed by Windows Update is damaged or missing.

0x8024402F – Network issues are preventing the update from downloading.

0x800F0922 – The computer does not have enough disk space or cannot connect to the update server.

0x800705B4 – The update took too long to download or install.

How to Interpret Error Messages

Error messages accompanying update failures can be cryptic, but understanding them is key to diagnosing the problem. Here are some steps to interpret these messages:

  1. Note the Error Code: Write down the error code displayed in the message.
  2. Search the Error Code: Use a search engine or the Microsoft support website to find more information about the error code.
  3. Check Context: Look at what was happening when the error occurred. Were you downloading the update, installing it, or restarting your computer?
  4. Follow Recommended Actions: Many error messages include recommended actions or links to troubleshooting steps. Follow these instructions to resolve the issue.

How to Troubleshoot Windows Update Installation Failures

Preliminary Checks

Before diving into detailed troubleshooting steps, it’s important to perform some preliminary checks. These initial steps can often resolve the issue quickly and easily.

Ensuring Sufficient Disk Space

Check Disk Space: Ensure that your system drive has enough free space. Windows updates typically require several gigabytes of free space to download and install. To check disk space:

  • Open File Explorer.
  • Right-click on the system drive (usually C:).
  • Select Properties.
  • Check the available space.

Free Up Space: If space is low, consider deleting unnecessary files, uninstalling unused programs, or moving large files to an external drive.

Restarting the Computer

Simple Restart: Sometimes, a simple restart can resolve temporary issues that are preventing the update from installing. Restart your computer and try running Windows Update again.

Checking Internet Connection

Stable Connection: Ensure you have a stable internet connection. A wired connection is often more reliable than Wi-Fi for downloading large updates.

Network Troubleshooter: Use the built-in network troubleshooter to diagnose and fix internet connectivity issues:

  • Go to Settings > Network & Internet > Status.
  • Click on Network troubleshooter and follow the prompts.

Temporarily Disabling Antivirus Software

Antivirus Interference: Sometimes, antivirus software can interfere with the update process. Temporarily disable your antivirus software and try running the update again. Remember to re-enable it after the update completes to ensure your system remains protected.

Step-by-Step Troubleshooting Guide

If the preliminary checks do not resolve the issue, proceed with the following detailed troubleshooting steps.

Running the Windows Update Troubleshooter

Accessing the Troubleshooter: The Windows Update Troubleshooter is a built-in tool designed to detect and fix common update issues. To run it:

  • Go to Settings > Update & Security > Troubleshoot.
  • Select Windows Update and click on Run the troubleshooter.
  • Interpreting Results: Follow the on-screen instructions and allow the troubleshooter to identify and fix issues. It will provide a report detailing any problems found and actions taken.

Resetting Windows Update Components

Resetting Components: Resetting the Windows Update components can fix various issues related to update failures. This process involves stopping the Windows Update services, renaming the SoftwareDistribution and Catroot2 folders, and restarting the services. Here are the steps:

  • Open Command Prompt as an administrator.
  • Run the following commands one by one:


net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

ren C:WindowsSoftwareDistribution SoftwareDistribution.old

ren C:WindowsSystem32catroot2 catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver


  • Outcome: After resetting the components, try running Windows Update again.

Deleting Temporary Update Files

Using Disk Cleanup Tool: Deleting temporary files can resolve issues caused by corrupted update files. To use the Disk Cleanup tool:

  • Open Disk Cleanup by typing it in the search bar.
  • Select the system drive (C:).
  • Check the boxes for Windows Update Cleanup and other unnecessary files.
  • Click OK and then Delete Files.

Manually Deleting Files: You can also manually delete files from the SoftwareDistribution folder:

  • Navigate to `C:WindowsSoftwareDistributionDownload`.
  • Delete all files in the folder.

Updating Device Drivers

Importance of Updated Drivers: Outdated drivers can cause conflicts with Windows updates. Ensure all your device drivers are up to date.

Updating through Device Manager:

  • Open Device Manager by typing it in the search bar.
  • Right-click on a device and select Update driver.
  • Choose Search automatically for updated driver software.

Manufacturer Websites: For the latest drivers, visit the hardware manufacturer’s website and download the appropriate drivers.
