We will provide a clear, step-by-step path for how to fix windows update issues, empowering you to resolve these problems yourself and get your system back to running smoothly and securely.
Windows updates are critical for the security and stability of your operating system, delivering everything from vital security patches to new features. When they fail, it’s more than an inconvenience; it can leave your system vulnerable. The good news is that most of these problems are fixable. The key to how to fix windows update issues is to work through solutions methodically, starting with the easiest fixes first.
Start with the Basics: Simple Steps That Often Work
Before diving into complex troubleshooting, it’s always best to start with the fundamentals. These simple checks can often resolve the problem without needing more advanced intervention and are a great starting point for anyone learning how to fix windows update issues.
Restart Your Computer
This is the oldest trick in the IT book for a good reason: it works. A simple reboot can resolve many temporary glitches or conflicts that may be preventing an update from installing correctly. An already-downloaded update might just be waiting for a restart to apply itself. After your computer boots up again, try running Windows Update manually.
Check Your Internet Connection
Windows Update requires a stable internet connection to download update packages. If your connection is slow or intermittent, downloads can fail or become corrupted. Ensure your Wi-Fi or Ethernet is working correctly before attempting to update again.
Ensure You Have Enough Disk Space
Large feature updates, in particular, require a significant amount of free disk space to download and install. If your main drive (usually C:) is nearly full, the update process will fail. Error codes like 0x80070070 often indicate insufficient disk space. You can free up space by using the built-in Disk Cleanup tool or by uninstalling unnecessary applications and deleting large files.
The Official Method: How to Fix Windows Update Issues with the Troubleshooter
Microsoft provides a built-in tool specifically designed to diagnose and automatically fix common update problems. Running the Windows Update Troubleshooter should always be one of your first steps. This is a primary method for how to fix windows update issues and is often highly effective.
For Windows 11
- Click the Start menu and go to Settings.
- Navigate to the System section, then click on Troubleshoot.
- Select Other troubleshooters.
- Under the “Most frequent” section, find Windows Update and click the Run button next to it.
- Follow the on-screen instructions and let the troubleshooter detect and resolve any problems. After it finishes, restart your PC and check for updates again. This process is a core part of how to fix windows update issues.
For Windows 10
- Click the Start menu and go to Settings.
- Select Update & Security.
- Click on Troubleshoot from the left-hand menu, then select Additional troubleshooters.
- Under the “Get up and running” section, click on Windows Update and then Run the troubleshooter.
- Allow the process to complete, restart your computer, and then try updating again.
Clearing the Decks: Deleting the Windows Update Cache
Sometimes, the files downloaded for an update can become corrupted, causing the process to fail repeatedly. A powerful way to solve this is to clear the Windows Update cache. This forces your system to download fresh, uncorrupted copies of the update files. This technique is an essential part of any guide on how to fix windows update issues.
- Press the Windows key + R to open the Run dialog box. Type
services.mscand press Enter. - In the Services window, scroll down to find the Windows Update service. Right-click on it and select Stop.
- Next, open File Explorer and navigate to
C:\Windows\SoftwareDistribution. - Select all the files and folders inside this directory and delete them. These are temporary update files and are safe to remove.
- Go back to the Services window, right-click the Windows Update service again, and this time select Start.
- Restart your computer.
After rebooting, Windows will recreate this folder and its necessary components. This fresh start is often exactly what’s needed for those wondering how to fix windows update issues.
Repairing the Foundation: How to Fix Windows Update Issues by Repairing System Files
If the problem persists, it could be caused by corrupted core system files on your computer. Windows includes powerful command-line tools to scan for and repair these files. Learning to use them is a more advanced but highly effective lesson in how to fix windows update issues.
To use these tools, you must open Command Prompt as an administrator. Search for “cmd” in the Start menu, right-click on Command Prompt, and select Run as administrator.
Running the DISM Command
The Deployment Image Servicing and Management (DISM) tool is used to repair the underlying Windows system image that other tools, like SFC, rely on.
- In the administrator Command Prompt window, type the following command and press Enter:
DISM.exe /Online /Cleanup-image /Restorehealth - This process may take several minutes to complete. Let it run without interruption.
Running the SFC Scan
After DISM has finished, you should run the System File Checker (SFC) tool. This tool scans all protected system files and replaces corrupted versions with correct ones.
- In the same Command Prompt window, type the following command and press Enter:
sfc /scannow - The scan can take 15-30 minutes. Once it’s complete, restart your computer.
Running these two scans in order is a robust method for anyone who needs to know how to fix windows update issues caused by system file corruption.
The Advanced Reset: Manually Resetting Update Components
If the previous methods haven’t worked, you can perform a more forceful and thorough reset of all Windows Update components. This is an advanced technique that involves stopping multiple services and renaming key system folders. This comprehensive approach is a powerful way for how to fix windows update issues that are particularly stubborn.
- Open Command Prompt as an administrator.
- Stop the BITS, Cryptographic, MSI Installer, and Windows Update Services by typing the following commands, pressing Enter after each one:
net stop wuauservnet stop cryptSvcnet stop bitsnet stop msiserver - Next, rename the
SoftwareDistributionandCatroot2folders. These folders store update components and signatures. Renaming them forces Windows to create fresh ones. Type the following commands, pressing Enter after each:ren C:\Windows\SoftwareDistribution SoftwareDistribution.oldren C:\Windows\System32\catroot2 Catroot2.old - Finally, restart the services you stopped earlier. Type these commands, pressing Enter after each:
net start wuauservnet start cryptSvcnet start bitsnet start msiserver - Close the Command Prompt and restart your computer.
This manual reset is one of the most effective solutions available for how to fix windows update issues.
A Direct Approach: Manually Downloading and Installing Updates
If a specific update consistently fails to install through the automatic process, you can try downloading and installing it manually from the Microsoft Update Catalog. This often bypasses the issue causing the failure. This is a very direct way for how to fix windows update issues.
- Go to Settings > Update & Security > Windows Update and click on View update history. Note the KB number of the failing update (e.g., KB5017271).
- Go to the Microsoft Update Catalog website in your browser.
- Search for the KB number you noted.
- Download the correct version for your system (e.g., x64 for 64-bit Windows) and run the installer file manually.
For users who are tired of automated failures, this manual solution is a go-to for how to fix windows update issues.
Real Life Examples
Scenario 1: The “Stuck on Downloading” Loop
The Problem:
A university student, Sarah, noticed her laptop was running slowly. When she checked for updates, she saw that a critical security update was stuck at 25% and had not moved for hours. She restarted her computer multiple times, but each time she checked, the update remained stuck at the same percentage, preventing any other updates from coming through.
The Solution:
Frustrated, Sarah followed the steps to clear the Windows Update cache. She stopped the Windows Update service through services.msc, navigated to the C:\Windows\SoftwareDistribution folder, and deleted its contents. After restarting the service and her laptop, she ran Windows Update again. This time, the download started from 0% and completed successfully within 15 minutes. The corrupted, partially downloaded files had been causing the endless loop.
Scenario 2: The “Update Fails with a Vague Error Code” Issue
The Problem:
Mark, who works from home, kept receiving an error code (0x80073712) every time he tried to install the latest Windows 10 feature update. The update would download completely, appear to install, and then fail at the last moment before rolling back the changes. The error message provided no useful information.
The Solution:
Suspecting that some of his core system files might be corrupted, Mark opened Command Prompt as an administrator. He first ran the DISM.exe /Online /Cleanup-image /Restorehealth command to repair the Windows image. After that completed, he ran sfc /scannow. The SFC scan found and repaired several corrupted system files. Following a final restart, he attempted the update one more time, and it installed without any errors.
Scenario 3: The Update That “Broke” Other Things
The Problem:
After a recent cumulative update, David found that his printer and Wi-Fi had stopped working. He tried reinstalling the drivers, but nothing helped. Realizing the problems started immediately after the update, he suspected the patch itself was the culprit, containing a bug that conflicted with his hardware.
The Solution:
David navigated to the “View update history” section in his settings and found the KB number of the most recent update. He then used the “Uninstall updates” feature to remove that specific patch. As soon as his computer restarted, both his printer and Wi-Fi began working perfectly again. He paused Windows updates for a week, giving Microsoft time to release a revised, fixed version of the patch before he tried updating his system again.
