If you would like to avoid this guessing game and save time, we highly advise you to try a powerful PC repair application [d1], which can perform numerous troubleshooting steps mentioned below and apply them automatically for you.

Fix 1. Run Windows Update troubleshooter

This solution is particularly useful for those who are experiencing errors or issues when trying to download or install updates. It is a straightforward process that requires minimal technical knowledge.

• Type Troubleshoot in Windows search.
• Select Additional troubleshooters.
• Find Windows Update from the list.
• Click it and select Run the troubleshooter.
• Apply the suggested fixes and restart your computer.

Fix 2. (Re)start relevant services

Windows Update relies on several services to run correctly, including the Windows Update service itself, Background Intelligent Transfer Service (BITS), and Cryptographic Services. Restarting these services can resolve issues where updates are not being downloaded or installed properly. 

• Type in Services in Windows search and press Enter.
• Locate Background Intelligent Transfer Service (BITS).
• If it is already running, right-click and select Restart.
• If the service is not running, double-click it, and pick Automatic under the Startup type from the drop-down menu.
• Click Start, Apply, and OK.
• Repeat this process with Windows Update and Cryptographic services.

Fix 3. Perform Disk Cleanup

Disk Cleanup is a utility that removes unnecessary files from your hard drive, which can free up space and potentially fix issues preventing updates from being installed.

• Type Disk Cleanup in Windows search and hit Enter.
• If your Windows is installed on drive C, pick it from the list (should be by default) and press OK.
• Click Clean up system files.
• Select your main disk again and click OK.
• Here, select the largest portions of the data used - these typically include Temporary Internet Files, Windows Update, Temporary Files, Recycle Bin, Delivery Optimization Files, and others.
• Click OK - the process should be finished shortly.

Fix 4. Reset Windows Update Components

Resetting Windows Update components can help resolve issues by essentially refreshing the update process, and clearing out any corrupted update files or configurations that could be causing problems.

• Type in cmd in Windows search.
• Right-click on Command Prompt and select Run as administrator.
• User Account Control will ask you whether you want to allow to make changes to the system - click Yes.
• Copy and paste each of these commands, pressing Enter each time:
  net stop bits
  net stop wuauserv
  net stop appidsvc
  net stop cryptsvc
  Del “%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*”
  rmdir %systemroot%\SoftwareDistribution /S /Q
  rmdir %systemroot%\system32\catroot2 /S /Q
  regsvr32.exe /s atl.dll
  regsvr32.exe /s urlmon.dll
  regsvr32.exe /s mshtml.dll
  netsh winsock reset
  netsh winsock reset proxy
  net start bits
  net start wuauserv
  net start appidsvc
  net start cryptsvc 
• Restart your device.

Fix 5. Repair corrupted files

Running SFC and DISM scans can restore the integrity of system files and facilitate a smooth update process.

• Open Command Prompt as administrator.
• In the Command Prompt window, paste the following command and hit Enter:
  sfc /scannow
• Next, use these commands (don't forget to press Enter every time):
  Dism /Online /Cleanup-Image /CheckHealth
  Dism /Online /Cleanup-Image /ScanHealth
  Dism /Online /Cleanup-Image /RestoreHealth
• Restart your device.

Fix 6. Install the update manually

If automatic updates are not working, you can manually download and install the update from the Microsoft Update Catalog. This method involves searching for the specific update that is causing issues and installing it directly.

• Go to the official Microsoft Update Catalog website.
• Type the KB5034763 into the search bar, and click Search.

• After picking the correct version, click the Download button and proceed with the on-screen instructions.
• Restart your computer to implement the new updates.

Fix 7. Use the Media Creation tool

The Media Creation Tool can be used to upgrade your system to the latest version of Windows. This tool is particularly useful when you are unable to update Windows through the usual update process.

• Visit the official Microsoft website and download Windows 10 installation media.
• Double-click the installer and click Yes when the User Account Control window shows up.
