Let’s see how to fix the error 0x80070490 when upgrading from Windows 11 Home to Pro.

Cause

0x80070490  (“Element not found”) is a CBS/CSI error, which indicates there is a problem with the component store (i.e., the WinSxS folder and the registry.)

You can resolve this error by running a component store cleanup.

Resolution

To fix the error code 0x80070490 when upgrading from Windows 11 Home to Pro, follow the steps below:

First, ensure that the system is connected to the internet.

Open an admin Command Prompt window and run the following commands one by one:

DISM /Online /Cleanup-Image /StartComponentCleanup

DISM /Online /Cleanup-Image /RestoreHealth

SFC /SCANNOW
Editor’s note: The 1st command (i.e., StartComponentCleanup) should be enough in most cases. If that doesn’t do the trick, run the 2nd and the 3rd commands in addition.

Screenshots

The output screenshots are provided below for reference. You should see the “The operation completed successfully” output for each DISM command. If the 1st command stalls at 20%, see the article DISM StartComponentCleanup Stops at 20% to fix the issue.
