How Can I Solve The Windows 10 Update Error Code 0x80070020?

Run Update Troubleshooter

If none of the other solutions worked, you should try running Microsoft’s official Update Troubleshooter. This tool resolves several update-related issues and may also solve your problem. To run the Windows Update troubleshooter, follow these steps:

1 – Download Microsoft’s Windows Update Troubleshooter.

2 – Run the tool and follow the instructions on the screen.

3 – Now, try to install the update again.

Restart BITS

Well, Background Intelligent Transfer Service (BITS) is a Windows process that is in charge of sending updates to your computer. As a result, if this process becomes corrupt, you will have problems obtaining updates. Therefore, we need to restart BITS and run Windows Update to get things working again. What you must do is as follows:

1 – Enter services.msc by pressing Windows Key + R. Enter or click OK to continue.


2 – Now, Find Background Intelligent Transfer Service. Open Properties by right-clicking.


3 – On the General tab, look for Startup type and select Automatic.

4 – If the BITS is not already running, right-click and select Start.


5 – Lastly, Confirm the selection and close the window.

If nothing is wrong with BITS, try another solution.

Reset Windows Update Services

Windows Update relies on several services to function correctly, and resetting Windows Update services may be able to resolve any issues. This reasonably simple order requires you to run a few commands in Command Prompt. To accomplish this, follow these steps:

1 – First, Start Command Prompt as administrator. 

2 – Launch Command Prompt and run the following commands:

  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
  • net start wuauserv
  • net start cryptSvc
  • net start bits
  • net start msiserver

Check to see if the Windows Update problem has been resolved after running these commands. If you don’t want to input all these commands manually, you may use the Windows Update reset script to perform this solution.


Although many users believe the SFC scan to be an overrated solution, it may be useful in specific instances. If you’re unfamiliar with this tool, it searches your computer for issues and corrupted features and attempts to solve them (more or less) successfully. In Windows 10, follow these steps to run the sfc/scannow command:

1 – To open the Win + X menu, press Windows Key + X. Choose Command Prompt (Admin) or Powershell (Admin) from the list.


2 – In the command prompt, enter sfc/scannow.

3 – The process should take a few minutes.

4 – When finished, close the Command Prompt.

If the SFC scan fails to fix the problem, or if you cannot run the SFC scan at all, you may want to consider using the DISM scan instead. To perform a DISM scan, do the following:

1 – Run Command Prompt as administrator. 

2 – To run the command, type DISM /Online /Cleanup-Image /RestoreHealth and click Enter.

3 – The DISM scan will now start. Don’t interrupt the scan if it takes more than 20 minutes.

When the scan is done, check to see if the problem has been resolved. If the issue persists or you could not run the SFC scan previously, run it again. Again, check to see whether the issue has been resolved.

Disable Antivirus

Third-party antivirus software and Windows are not the greatest of friends. A third-party antivirus installed on your computer may cause more harm than good. This incompatibility can create problems with various Windows features, including Windows Update.

If you’re using a third-party antivirus, you could want to experiment with different settings to see if that helps. In rare circumstances, you may need to disable your antivirus to resolve this issue. However, even if you disable your antivirus, Windows 10 has its antivirus, Windows Defender, so your computer is safe.

In rare circumstances, you may have to uninstall your antivirus to solve this issue. However, if uninstalling the antivirus resolves the problem, you might consider switching to a new antivirus solution. Several excellent antivirus software solutions are entirely compatible with Windows 10 and will not interfere with it.

To Find The Faulty Services, Use Command Prompt

According to users, some services might occasionally interact with your system, resulting in error 0x80070020. You can, however, find these services by using Command Prompt. Do the following to do this:

1 – Run Command Prompt as administrator.

2 – Now, execute netstat -aon | find “:80” and netstat -aon | find “:443”. You’ll see a list of details. Examine the numbers on the right side. These numbers reflect the process IDs that are utilizing your network connection.

3 – To find a troublesome process, use Task Manager. You may accomplish this by hitting Ctrl + Shift + Esc at the same time.

4 – When Task Manager is launched, navigate to the Details tab and look at the PID column. Well, you should be able to find the same numbers you found in Step 2 there. Find the troublesome process, select it, and click the End task button.

5 – Return to the Services window and check for Step 2 in the PID column. Well, if you find a match, right-click the service with that PID and select Stop from the menu. Keep in mind that some services are necessary by Windows, so use caution while disabling them.

This is an advanced solution, so proceed with caution and carefully follow the instructions.

Perform An In-place Upgrade

If you cannot update Windows due to a 0x80070020 error, you should consider conducting an in-place upgrade. This process will install the most recent version of Windows while keeping all of your files and apps intact. You must do the following to perform an in-place upgrade:

1 – Go to Microsoft’s website and download the Media Creation Tool.

2 – After downloading Media Creation Tool, launch it.

3 – Choose Upgrade this PC now. 

4 – Wait for Media Creation Tool to prepare the required files.

5 – Choose Download and install updates and then click Next. Wait for updates to download.

6 – Follow the on-screen instructions until you reach the Ready to install screen. Click on Change what to keep. 

7 – Choose to Keep personal files and apps. Now click the Next button.

8 – The installation process will now start. To finish it, follow the instructions on the screen.

When the installation is complete, you will have the most recent version of Windows installed, and the problem should be resolved. That’s all there is to it; we hope this post helps you with error code 0x80070020 and that you can now install the new update normally.
