Most of the time Windows updates are automatic processes that require little to no intervention from users. This is especially true for Windows 10 and 11, as they’re configured to download and install important updates automatically.

That doesn’t mean you shouldn’t check for new updates regularly, especially since you might find your Windows update stuck at 0%. If your Windows update is taking forever, it’ll require your intervention. But don’t worry, you don’t need to be tech-savvy to troubleshoot and fix this issue.

    Why Is the Windows Update Stuck?

    Windows updates can get stuck during the download or installation process, and there are different reasons behind this problem. Here’s the list of the most common reasons why your Windows update might get stuck at 0%:

    1. Unstable internet connection. Slow and unstable internet connection is the top reason behind Windows updates getting stuck. Updates require a stable connection to download and install all the files properly. Check your internet connection and download speed. Reset your router if needed, and if you’re using WiFi, make sure your Windows device is close to the router so there are no signal interruptions.
    2. Insufficient disk space. Windows updates need a significant amount of disk space to download and install all the new files. If your PC doesn’t have enough storage space, the update process can easily get stuck. You must ensure you have at least 10GB of free space before beginning the Windows update process.
    3. Software or services conflict. If you’re running third-party applications on your PC or if some services are running in the background while your Windows is updating, they could cause the process to be stuck. You can easily fix this by disabling or uninstalling any conflicting software. You should also stop all non-essential background services.
    4. Corrupted update files. If the files Windows downloaded are corrupted, they can cause the update process to get stuck. The Windows Update Troubleshooter and the System File Checker (SFC) can help find and fix any corrupted files on your PC.
    5. Windows Update Service issue. Windows Update Service can become unresponsive for various reasons. This could be what’s causing the stop in the update process. Restarting the Update Service should fix this issue.
    6. Incompatible Updates. Some specific updates could be incompatible with your PC system and cause various issues during installation. If you think a specific update is causing the problem, try hiding it from the list of available updates, or if it’s already installed, simply uninstall it.
    7. Viruses and Malware can interfere with the Windows update process. They consume the system resources needed for the update or directly affect the update installation files. Run a malware or virus scan to detect possible problems.
    8. Outdated System Drivers can easily cause your Windows update process to get stuck at 0%. Make sure your drivers are up to date before you proceed with the Windows update.

    The most important thing is to be patient. Some Windows updates are large and the process can take even several hours. Before starting to troubleshoot the issue, make sure the update is stuck.

    If nothing has changed on your computer screen for around three hours since you started the update, it’s stuck. Your monitor might be displaying one of these messages:

    • Preparing to configure Windows. Do not turn off your computer.
    • Configuring Windows update x%complete. Do not turn off your computer.
    • Installing update x out of x. Please do not turn off or unplug your computer.
    • Getting Windows Ready. Don’t turn off your computer.
    • Stage 1 of 3.

    Any similar message might be displayed but with different wording. Now, let’s see how you can fix this issue.

    1. Wait It Out or Restart Your Computer

    As explained before, Windows updates can take quite a while. Sometimes, the best action is to take no action. Waiting can be necessary when it comes to Windows updates. If the new patch or a service pack is large, it could take up to several hours for your computer to download and install all the files. So be patient and wait.

    If you suspect the Windows update is taking too long due to the poor internet connection, you can try restarting your router and computer. This usually solves the issue. Typically, there will be no specific error message if an internet connection is causing problems with the update, so go ahead and restart your machine.

    2. Run Windows Update Troubleshooter

    Microsoft is aware of the various problems that can occur while Windows is updating, and that’s why it created the Windows Update Troubleshooter. Running this program takes several minutes because the troubleshooter will go through the whole operating system to find the possible problems and apply automatic repairs when possible. Follow these steps to run Windows Update Troubleshooter:

    Go to the Microsoft Support page and download the Troubleshooter. You can select to download and install this tool for Windows 10 or Windows 11. If there’s no download option, you already have the troubleshooter installed on your device.
