Why Does My Windows 10 Update Get Stuck at 0%?

Several things can cause your Windows 10 update to freeze at the 0% mark. It’s rarely a sign of a serious problem with your computer, but rather a hiccup in the process. Common culprits include:

  • Corrupted Update Files: Sometimes, the files needed for the update download incorrectly or get damaged. This prevents the installation process from starting.
  • Conflicting Software: Security software (like some antivirus programs) or other applications can sometimes interfere with the update process, thinking it might be a threat.
  • Disk Space Issues: Windows updates require a certain amount of free space on your hard drive to download and install. If your drive is too full, the update can’t proceed.
  • Network Connectivity Problems: A weak or unstable internet connection can interrupt the download of update files, leading to it getting stuck.
  • Problems with Windows Update Services: The background services that manage Windows updates might stop working correctly.
  • Driver Conflicts: Outdated or incompatible device drivers can sometimes prevent system updates from installing.

The Quickest Fixes: Restart and Reconnect

Before diving into more complex solutions, let’s try the simplest things first. Often, a simple restart or checking your internet connection can solve the problem.

1. Restart Your PC

This is the golden rule of troubleshooting computers, and it applies here too! A simple reboot can clear temporary glitches and allow the update process to start fresh.

  1. Go to the Start menu (click the Windows icon in the bottom-left corner).
  2. Click the Power icon.
  3. Select Restart.

Once your computer restarts, try checking for updates again. Go to Settings > Update & Security > Windows Update and click Check for updates.

2. Check Your Internet Connection

A stable internet connection is crucial for downloading updates. If your connection is slow or keeps dropping, the download might stall. Make sure your Wi-Fi is strong, or if you’re using a wired connection, ensure the cable is securely plugged in at both ends.

Tip: Try restarting your router and modem. Unplug them, wait about 30 seconds, and then plug them back in. This can clear up connection issues.

Fixing Corrupted Update Files and Services

If the basic steps don’t work, the problem might lie with the Windows Update components themselves. These next steps involve resetting and repairing these parts.

3. Run the Windows Update Troubleshooter

Microsoft provides a built-in troubleshooter designed to automatically detect and fix common Windows Update problems. It’s a lifesaver!

  1. Open Settings by pressing Windows key + I.
  2. Go to Update & Security.
  3. In the left-hand menu, select Troubleshoot.
  4. Click on Additional troubleshooters.
  5. Find and click on Windows Update, then click Run the troubleshooter.

Follow the on-screen prompts. The troubleshooter will scan for issues and attempt to fix them. Once it’s done, restart your computer and try checking for updates again.

4. Reset the Windows Update Components Manually

This is a more in-depth method that involves stopping the Windows Update services, renaming the folders where update files are stored (effectively resetting them to a default state), and then restarting the services. This is like clearing out the old, potentially corrupted update cache.

Important: You’ll need to run Command Prompt as an administrator for this. Make sure to follow the steps precisely.

  1. Right-click the Start button and select Command Prompt (Admin) or Windows PowerShell (Admin).
  2. If prompted by User Account Control, click Yes.
  3. In the Command Prompt window, type the following commands, pressing Enter after each one. These commands stop the necessary services:

    4. net stop wuauserv

    net stop cryptSvc

    net stop bits

    net stop msiserver

  4. Now, we’ll rename the SoftwareDistribution and catroot2 folders. Type these commands and press Enter after each:

    5. ren C:WindowsSoftwareDistribution SoftwareDistribution.old

    ren C:WindowsSystem32catroot2 catroot2.old

  5. (If you get an error that the folder can’t be renamed because it’s in use, make sure you’ve stopped all the services correctly in the previous step and try again.)
  6. Next, restart the services you stopped. Type these commands and press Enter after each:

    7. net start wuauserv

    net start cryptSvc

    net start bits

    net start msiserver

  7. Close the Command Prompt window by typing exit and pressing Enter.
  8. Restart your computer.

After restarting, go back to Settings > Update & Security > Windows Update and click Check for updates. Windows will re-download necessary files and should now be able to proceed.

Check Disk Space and System Files

A lack of disk space or corrupted system files can also halt updates in their tracks.

5. Free Up Disk Space

Windows updates can be quite large. If your C: drive is nearly full, the update won’t have the room it needs. Aim to have at least 15-20 GB of free space.

  1. Open File Explorer (Windows key + E).
  2. Click on This PC in the left pane.
  3. Right-click on your C: drive and select Properties.
  4. Under the “General” tab, you’ll see how much free space you have.

If space is low, consider using Disk Cleanup:

  1. Search for “Disk Cleanup” in the Windows search bar and open it.
  2. Select the C: drive if prompted.
  3. Check the boxes for files you want to remove (e.g., Temporary Internet Files, Downloads, Recycle Bin).
  4. Click Clean up system files to find even more space (like old Windows update files).
  5. Select C: drive again and proceed.
  6. Click OK and then Delete Files.

You can also manually uninstall unused programs or move large files (like photos or videos) to an external drive or cloud storage.

6. Run System File Checker (SFC) and DISM

These tools check for and repair corrupted Windows system files that might be interfering with updates.

  1. Open Command Prompt as Administrator (right-click Start, select Command Prompt or PowerShell).
  2. First, run the DISM (Deployment Image Servicing and Management) tool. Type the following command and press Enter:

    3. DISM /Online /Cleanup-Image /RestoreHealth

    This process can take several minutes and might seem like it’s stuck, but let it run to completion. It checks and downloads correct system files from Microsoft.

  3. Once DISM is finished, run the System File Checker. Type the following command and press Enter:

    4. sfc /scannow

    This command scans all protected system files and replaces incorrect versions with correct Microsoft versions. This can also take some time.

  4. When both commands are complete, restart your computer.

Now, try checking for Windows updates again.

When to Consider Other Methods

If the above steps haven’t resolved the issue, there are more advanced options. These typically involve ensuring your core Windows files are healthy and that no conflicting software is actively blocking the process.

7. Check for Conflicting Antivirus Software

While essential for security, some antivirus programs can be a bit overzealous and block legitimate system processes, including Windows updates. Temporarily disabling your third-party antivirus software during the update process can sometimes resolve this.

How to temporarily disable (examples):

  • Norton: Right-click the Norton icon in the system tray, select “Turn off Auto-Protect” and choose a time duration (e.g., 15 minutes).
  • McAfee: Right-click the McAfee icon, go to “Turn off” and select an option.
  • Avast: Right-click the Avast icon, select “Avast Shields Control,” and choose a duration.

Crucially, remember to re-enable your antivirus software immediately after checking for updates or after the update completes. For maximum security, it’s often best to rely on Windows Defender, which is integrated into Windows 10 and generally doesn’t cause update conflicts. You can check its status in Settings > Update & Security > Windows Security.

8. Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs. This helps you identify if a background program is interfering with your Windows update. If the update works in a clean boot environment, you’ll know one of your startup items is the culprit.

  1. Press Windows key + R to open the Run dialog box.
  2. Type msconfig and press Enter to open System Configuration.
  3. In the System Configuration window, go to the Services tab.
  4. Check the box that says Hide all Microsoft services.
  5. Click Disable all.
  6. Now, go to the Startup tab and click Open Task Manager.
  7. In Task Manager, for each startup item, select it and click Disable.
  8. Close Task Manager.
  9. Back in the System Configuration window, click Apply and then OK.
  10. You’ll be prompted to restart your computer. Do so.

After your computer restarts in a clean boot state, try checking for Windows updates one more time. If it works, the issue is with one of the disabled startup programs or services. You would then need to re-enable them incrementally to pinpoint the exact program causing the conflict.

Advanced Fixes: If Nothing Else Works

If you’ve tried everything above and your Windows 10 update is still stuck at 0%, consider these more involved solutions. They require a bit more caution but can be very effective.

9. Download the Update Manually from the Microsoft Update Catalog

Sometimes, the Windows Update service might struggle to download certain updates. You can often find individual updates on the Microsoft Update Catalog website and install them directly.

  1. First, you need to know the specific KB number (Knowledge Base article number) of the update that is stuck. Go to Settings > Update & Security > Windows Update. The update that is failing should be listed, along with its KB number (e.g., KB5012345).
  2. Open your web browser and go to the Microsoft Update Catalog.
  3. In the search bar, type the KB number (e.g., “KB5012345”).
  4. Find the correct update that matches your Windows 10 version (e.g., Windows 10 v21H2 64-bit) and click Download.
  5. A pop-up window will appear. Click the link for the download (usually the first one).
  6. Save the file (it will be an .msu file) to your Downloads folder or another convenient location.
  7. Double-click the downloaded .msu file to start the installation.
  8. Follow the on-screen prompts.

After installation, restart your PC and check for updates again. The problematic update should now be installed.

10. Use the Media Creation Tool to Upgrade

If even manual downloads fail, a more drastic but often successful approach is to use the Windows Media Creation Tool. This tool allows you to download the latest version of Windows 10 and perform an “in-place upgrade,” which reinstalls Windows while keeping your files, settings, and applications.

Before you begin:

  • Ensure you have a stable internet connection.
  • Back up important files just in case.
  • You’ll need sufficient free space on your C: drive (at least 10-15 GB).
  1. Go to the official Microsoft Windows 10 download page.
  2. Under “Create Windows 10 installation media,” click Download tool now.
  3. Save the MediaCreationTool.exe file.
  4. Run the tool by double-clicking it. Accept the license terms.
  5. When asked “What do you want to do?”, select Upgrade this PC now and click Next.
  6. The tool will download Windows 10, check for updates, and prepare the installation. This can take some time.
  7. When prompted, ensure Keep personal files and apps is selected. This is crucial for an in-place upgrade.
  8. Click Install.

Your computer will restart several times during this process. Once it’s complete, you’ll have the latest version of Windows 10 installed, and hopefully, your update issues will be resolved.
