Ways to Fix Update Error Code 0x80240020 in Windows 10

To solve the Update error 0x80240020 on Windows 10 PC, use the following workarounds –

2] Run Windows Update Troubleshooter

Since this update issue is due to corrupt device drivers, following the above fixes should resolve the underlying cause.

3] Enable the BITS service

Background Intelligent Transfer Service (BITS) acts as the communicator between Microsoft’s servers and your PC.  This is why if anything goes wrong or this service is stopped, you won’t be able to receive new patch-updates by the company servers.

  • Hit the Search button and type services.msc in the text field. Click the top result to start Services.
  • Now locate and double-click on the Background Intelligent Transfer Service.
  • On the next screen, go to the service status and see its running status. This should display “Started”.
  • However, if stated otherwise like “Stopped”, click Start thereafter OK.

4] Delete/Recreate the SoftwareDistribution folder

Many a time, the system doesn’t perform an upgrade owing to some missing or corrupt files. In such cases, one should definitely try to delete and recreate the SoftwareDistribution folder. Performing so does not only solve the error 0x80240020 but fixes several other update-related issues. Here’s how to proceed –

  • Press Win and R shortcut to invoke the Run dialog.

Windows Update service, Background Intelligent Transfer service, and Cryptographic services.

If none of the fixes above resolve the error 0x80240020, tweaking key values of certain entries inside the registry may solve this issue. However, be careful as any incorrect changes may corrupt the entire operating system. We also suggest creating a system backup before processing the below steps –

  • Make a right-click on the Windows icon and select Run.
  • Type regedit near the blinking console and press Enter to start Registry Editor.
  • When the UAC window appears, tap Yes to authorize the access.
  • Now, expand the folders present on the left column to reach out to the following address –

Right click on WindowsUpdate > Select New > Key


  • After entering the newly created key, right-click anywhere and select New > DWORD (32-bit) value.
