Complete Troubleshooter Guide to Fix Windows Update Errors Easily

Since Windows updates patch security vulnerabilities, add new features to the system, update drivers, and enhance the PC performance, we recently decided to perform one. However, we experienced a Windows update failure; our update kept failing until we followed the Windows Update troubleshooter, which fixed updates for many other users. 

If you are also experiencing problems updating your Windows operating system, you are in the right place. In this article, we guide you through quick, easy, tried-and-tested ways to repair Windows updates, ranging from a simple restart to resetting Windows. 

Before moving to these solutions, you must ensure your PC meets the pre-update requirements shared below. 

Prerequisites for Windows Update

If the following requirements are not met, Windows updates may fail on your computer. 

• You have a stable internet connection.
• Your system has free disk space of at least 10 to 15 GB.
• No external device is connected to your computer.
• If you are using a laptop, it is operating on AC power.
• Your system’s specifications meet the minimum requirements for the Windows update.

If your system checks all the above pre-update requirements, and you still encounter errors like 0x80070002 (the system cannot find the specified file), 0x80070003 (the system cannot find the specified path), 0x80070005 (access denied, indicating insufficient administrator permissions, 0x8024402F (Windows Update service not running), 0x80244022 (internet connectivity problems), and 0x80080005 (installation service issues), the causes of these errors and update failure may be one of the ones discussed below. 

Causes of Windows Update Errors

While Windows Update issues are not uncommon despite meeting all the requirements, several reasons may contribute to the update failure, such as the following. 

• The crucial system files may be corrupted or missing, preventing the update installation.
• Your computer may be trying to install several updates simultaneously.
• There may not be enough free disk space on your hard drive.
• Internet connection issues, such as an unstable or interrupted connection, may be responsible for incomplete update file downloads.
• Drivers, such as graphics drivers, may be outdated or incompatible, resulting in Windows update failure.

Now that you are familiar with the common reasons Windows updates fail, it will be easier for you to apply the Windows Update troubleshooter guide below. 

How to Fix Windows Updates

Below are the effective Windows update fixes you can apply sequentially until the Windows updates install successfully on your computer. 

Fix 1: Restart your computer

What do you do when you get tired? Rest and then start again. Sometimes, your computer may need a quick restart, too. Restarting the PC resolves the queued-up multiple updates that may be running simultaneously to fix the Windows update failure. Hence, you can follow the steps below to restart your PC. 

• First, right-click the Windows icon and hover over Shut down or sign out.
• Next, choose Restart from the menu that appears.

Fix 2: Run the Windows troubleshooter tool

Windows comes with a designated troubleshooting utility for Windows updates. Below is how to run the Windows Update Troubleshooting to solve various problems related to Windows updates.

• In this step, go to the Windows Update option and click the Run button next to it.
• Next, follow the on-screen instructions to fix the detected Windows Update issues.
• Lastly, restart your computer to complete the troubleshooting process.

Windows Update Troubleshooter failed to run on your PC due to a lack of storage space, corrupted update files, conflicting third-party software, problems with Windows update services, or other reasons? Then, you can fix it by following these steps. 

What to do if the Windows Update Troubleshooter is not working

Fix 5: Download and install the Microsoft Update Catalog patches manually

If you are stuck with a Windows update that does not install on your computer, you can download and install the latest cumulative update (LCU) manually from the Microsoft Update Catalog. Here is how. 

• First, search Windows update history (for your Windows version) in your favorite search engine. For example, if your computer runs Windows 11, search for Windows 11 update history.
• Next, open the Microsoft documentation for all supported Windows versions.
• In this step, note the KB number for the latest update in the top left of the Microsoft documentation.

• Now, navigate to the Microsoft Update Catalog.

• Next, click on the Download button for the Windows Update you wish to install.
• In this step, click on the link that appears on your screen and download the update file.
• Lastly, click on the downloaded file and follow the on-screen instructions to install the required Windows update.

Fix 6: Perform a system restore

If you have created a restore point for your system previously, you can revert your system to the state before Windows update errors. Here is how. 

• First, click on the taskbar Windows icon, type Control Panel in the search bar, and then click Control Panel in the search results to open it.
• Once the Control Panel opens, change its view to Large icons or Small icons.
• In this step, click the Recovery option from the Control Panel menu and then choose Open System Restore.
• Now, click Next when the System Restore window appears.
• Next, select the restore point before the Windows update problems begin.
• In this step, click Next and then click on the Finish button.

• Lastly, when you get a final confirmation prompt on your screen, click Next to start the system restoration process. Once this process finishes, your computer will restart.

Fix 7: Update device drivers

Outdated drivers can also cause Windows updates to fail. Hence, if you have added any hardware to your computer, below is how to update the driver for it. 

• Begin by right-clicking on the Windows icon and selecting Device Manager from the on-screen options.

• When the Device Manager window appears on your screen, double-click on the category of the recently added hardware. For example, if you recently added a graphics card, double-click Display Adapters.
• Next, right-click on the hardware and choose Update Driver from the on-screen options.
• Now, search automatically for drivers.
• In this step, follow the on-screen prompts to complete the driver download and installation.
• Lastly, complete the driver download and installation by restarting your computer.

Fix 8: Free up space on your drive

Since the non-availability of enough disk space can be a reason for failed Windows updates, ensure your PC has enough space. You need at least 16 GB of free space to update a 32-bit OS, or 20 GB for a 64-bit OS. To free up space in Windows 11/10, you can use one of the best disk cleaner software available. 

Fix 9: Try an in-place Windows upgrade

Windows 11 has a relatively hidden but useful feature that allows you to download the latest version of Windows without wiping out everything on your computer, including applications, files, and data. Below is how to use this feature. 

• First, open Settings using the Windows+I keyboard shortcut.
• Second, navigate to the Windows Update settings.
• Next, choose Advanced Options.
• In this step, click Recovery and then click Fix problems without resetting your PC.
• Lastly, click on the Reinstall now button.
