Solution 2 – Restart BITS

Background Intelligent Transfer Service (BITS) is a Windows process responsible for delivering updates to your computer. So, if this process gets corrupt, you’ll have problems receiving updates. In order to make it work again, we should restart BITS, and try to run Windows Update once again.

Here’s exactly what you need to do:

Press Windows Key +R and enter services.msc. Press Enter or click OK.
Find Background Intelligent Transfer Service. Right-click and open Properties.
On the General tab, find Startup type and choose Automatic.
If the BITS is not running, right-click and choose Start.
Confirm selection and close window.

If nothing’s wrong with BITS, move on to another solution.

Solution 3 – Reset Windows Update services

Windows Update relies on various services in order to work properly, and if there are any issues with Windows Update, you might be able to fix them by resetting Windows Update services.

This is relatively straightforward, and in order to do this, you need to run a few commands in Command Prompt. To do that, follow these steps:

Start Command Prompt as administrator.
When Command Prompt starts, run the following commands:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv

Solution 4 – Perform SFC/SCANNOW

Although many users consider the SFC scan an overrated solution, it might be helpful in some cases. In case you’re not familiar with this tool, it scans your computer for issues and corrupted features, and tries to solve them (more or less) effectively.

Here’s how to run the sfc/scannow command in Windows 10:

Press Windows Key + X to open Win + X menu. Select Command Prompt (Admin) or Powershell (Admin) from the list.
In the command line type sfc/scannow

The process should last a few minutes.
After it’s done, close the Command Prompt.

Start Command Prompt as administrator.
Enter DISM /Online /Cleanup-Image /RestoreHealth and press Enter to run the command.
DISM scan will now start. The scan can take about 20 minutes or more, so don’t interrupt it.

Once the scan is finished, check if the problem is resolved. If the issue is still present, or if you were unable to run SFC scan before, be sure to repeat the SFC scan. After doing that, check if the issue is resolved.

Solution 5 – Run Update troubleshooter

If none of the solutions listed above managed to solve the problem, you should try running Microsoft’s official Update Troubleshooter. This tool solves various update-related issues, and it might solve your problem, as well. Here’s what you need to do to run Windows Update troubleshooter:

Solution 6 – Use Command Prompt to find the problematic services

According to users, sometimes certain services can interfere with your system and cause error 0x80070020 to appear. However, you can find these services by using Command Prompt. To do that, just do the following:

Start Command Prompt as an administrator.
Now run netstat -aon | find “:80” and netstat -aon | find “:443” commands. You’ll see a list of information. Look at the numbers at the right side. These numbers represent the ID of the processes that are using your network connection.
To find a problematic process, you need to open Task Manager. You can do that by pressing Ctrl + Shift + Esc.
When Task Manager opens, go to the Details tab and look at the PID column. There you should be able to find the same numbers you got in Step 2. Find the problematic process, select it and click End task.
Now go to Services window and check the PID column for any numbers from Step 2. If you find a match, right-click the service with that PID, and choose Stop from the menu. Keep in mind that certain services are required by Windows, so be cautious while disabling services.
