windows update failed to install or download

It’s always a good idea to keep your Windows system fully updated, both to prevent unnecessary issues as well as to get new features on your system. However, sometimes Windows fails to download or install the update.

It can occur due to various reasons such as issues with services, drivers, and third-party programs, corruption of your system files, and so on. Since there are many causes, there are correspondingly varied solutions for each case.

In this article, we have mentioned the most common causes for this error while providing their corresponding solutions.

Causes for Windows Failing to Install or Download Updates

Here are some of the potential causes for Windows failing to install or download system or optional updates:

  • Lack of enough disk space.
  • Incorrect date and time settings.
  • Issues with update services.
  • Corrupt downloaded update files.
  • Third-party antivirus blocking the process.
  • Conflicts due to incompatible apps and drivers.
  • System file corruption

How to Fix Windows Update Failed to Install or Download?

First, restart your PC and try the update again by clicking Retry or Install now on the Update Settings (ms-settings:windowsupdate on Run). If you still encounter the error, you need to follow the possible solutions we have mentioned below to resolve your issue.

Disconnect Peripheral Devices

The drivers or firmware of some external devices may conflict with the files an update is trying to install on your system. In such cases, the process can’t complete leading to this issue.

disconnect-devices

You can simply disconnect your peripheral devices while undergoing system updates to avoid such errors. If it’s a device you really need, such as a mouse, you can try using other devices in place of your original one to check for such issues.

Free Disk Space

You also need to have enough space on your system drive in order to download update files. So, if its free space is low, delete or transfer unnecessary files to make enough space available for the update. You can also refer to our article on How to Clean C Drive to learn about additional things you can do for this purpose.

Check Date and Time

Microsoft’s server checks the local time on your system before providing you with the update files. If there are large differences between the time on your computer and that of the server, it won’t provide you with the files for security purposes.

As such, your system fails to download the update. So, you need to maintain the proper date and time on your PC. To do so,

  1. Right-click on the date and time on your taskbar (right-side) and select Adjust date and time.
  2. Toggle On Set time zone automatically. If it shows an incorrect time zone, turn it Off and manually set the proper one.
  3. Enable Set time automatically.
    set-time-and-time-zone-automatically
  4. Click on Sync now.

Run Windows Update Troubleshooter

Windows comes with dedicated troubleshooters that help you in resolving many system issues. It also includes the Windows Update troubleshooter, which you can run whenever you encounter any update issues. Here’s how you can do so:

  1. Open Run by pressing Win + R.
  2. Type ms-settings:troubleshoot to open Troubleshoot Settings.
  3. Click on Other troubleshooters or Additional troubleshooters.
  4. Select Run next to Windows Update (Windows 11) or select Windows Update > Run this troubleshooter (Windows 10).
    windows-update-troubleshooter
  5. Follow the on-screen instructions.

Reset Update Components

It is possible that the necessary services for the update process are not starting properly or have gotten stuck. Additionally, the update files those services downloaded may be incomplete or corrupt, causing the update to fail.

You can resolve both situations by resetting the update components. Here, you restart the services while deleting all pre-downloaded files in order to allow your system to start the download process all over again. Here’s what you need to do:

  1. Open Run.
  2. Type cmd and press Ctrl + Shift + Enter to open the Elevated Command Prompt.
  3. Enter the following commands:
    • net stop appidsvc
    • net stop bits
    • net stop cryptsvc
    • net stop wuauserv
      stop-update-services
    • del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"
      (If you don’t get access or the file/directory doesn’t exist, enter the command:
      del "%ALLUSERSPROFILE%\Microsoft\Network\Downloader\qmgr*.dat")
      delete-qmgr-dat
    • rmdir %systemroot%\SoftwareDistribution /S /Q
    • rmdir %systemroot%\system32\catroot2 /S /Q
      remove-softwaredistribution-and-catroot2
  4. If you can’t remove the folders, the services you stopped earlier (net stop commands) have restarted. So, run them again and then remove the folders using the rmdir command.
  5. Then continue entering the commands below to reset the Winsock Catalog and then restart the above service:
    • netsh winsock reset
      netsh-winsock-reset
    • net start appidsvc
    • net start bits
    • net start cryptsvc
    • net start wuauserv

Restart your PC and try updating your system again.

Disable Third-party Antivirus

Some third-party security programs may stop your system from downloading or installing some update files by considering them as threats even when they are safe. You can avoid this issue by temporarily disabling those applications until you successfully install the updates.

The process to do so differs between the various applications. So, it’s better to check official sources if you need more information.

Disable Startup Apps and Services

Some of your active applications can also conflict with the update process because of compatibility issues. You need to end all active processes that are not necessary to run the OS and try updating again to resolve them.

The easiest way to do so is to disable the startup processes and reboot your system before installing updates. Here are the necessary steps:

  1. Open Run.
  2. Type msconfig and press Enter to open System Configuration.
  3. Go to the Services tab.
  4. Check Hide all Microsoft services and click Disable all.
    hide-all-microsoft-services
  5. Click Apply and then go to the Startup tab.
  6. Hit Open Task Manager.
  7. Here, select each Enabled program (see the Status column) and click Disable.
    disable-startup-task-manager

Restart your system and try running the update again.

Repair Corrupt System Files

Another possible reason for this issue is due to corrupt system files or drive sectors. The update process requires many system programs to be running, so you need to repair all such corruption.

You can use the Deployment Image Servicing and Management (DISM) and the System File Checker (SFC) to repair corrupt system files and the Disk Checking tool (CHKDSK) to repair corrupt boot sectors. To do so,

  1. Open the Elevated Command Prompt.
  2. Enter the following commands:
    • dism /online /cleanup-image /restorehealth
    • sfc /scannow
    • chkdsk /r /x C:
      dism-sfc-chkdsk

Update Drivers

Corrupt or problematic drivers can also stop your system from installing Windows updates. The updates also include changes to the driver or related system files, which is not possible if the driver restricts such actions. You need to update all your drivers to resolve such issues. Here’s how you can do so:

  1. Open Run.
  2. Type devmgmt.msc and press Enter to open the Device Manager.
  3. Expand the categories and right-click on individual devices.
  4. Click on Update driver and then Search automatically for drivers.
    update-microphone-driver

Update Using Update Assistant or Media Creation

If you can’t update your system through the built-in settings, you can use the Update Assistant for this purpose. However, keep in mind that you can only use it for Windows 10 as of the date of this article’s publishing. Here’s what you need to do:

  1. Go to Microsoft’s Windows Download webpage and select your Windows version.
  2. First, use the Update Assistant using the steps below:
    • Select Update Now.
      windows-10-assistant-update-now
    • Run the downloaded installer and follow the instructions.
  3. If you can’t install the update, you can use Media Creation by following the steps below:
    • Select Download tool now.
    • Run the setup.
    • Confirm UAC prompt and Accept the license terms.
    • Tick Upgrade this PC now and select Next.
      upgrade-this-pc-now
    • Click Change what to keep to see what changes the process will make and modify them if necessary.
    • Go back to the previous page and choose Install.
