While updating Windows, you may encounter an update failure with an error code
0x80070490. Although this error is usually resolved by a simple update restart, it can sometimes persist for a longer period of time.
Now, this may happen due to corrupt files in the system component store or issues with the Component-Based Servicing (CBS). If the issue is related to the update components, resetting them may solve the problem. However, this error may also arise from antivirus interfering with your updates or corrupt system files.
