To fix the problem you need to reset the windows update components. To reset the windows update components follow the steps from this link.


The only viable solution to this problem by my knowledge is that you have to wipe the disk clean and reinstall the complete OS. This way you might lose some data but you won’t get this error and this works in all cases. Try copying the data or making backup, this would help save your data.

Solution For Microsoft Error Code 80070490 Error


According to Microsoft support, Windows Update error “80070490” is related to a problem with the CBS Manifest file. This error can happen if the CBS manifest or the Component-Based Servicing is corrupt when you are updating your operating system using Windows Update or Microsoft Update.

You may encounter this error on Windows XP, Windows Vista, Windows 7, and Windows 8.x and all of these operating systems have the same solution, by running the System File Checker tool. The System File Checker tool or SFC is a built-in utility in Microsoft Windows that scans all protected system files.

When an incorrect version is detected, which normally happens when a file is corrupt, the tool replaces them with the correct Microsoft version. This tool normally requires the user to insert the Windows setup disc because the tool needs to copy the required DLL files from the disc to the system drive.

To run the SFC tool, in Windows 7, click “Start”, “All Programs”, “Accessories” then right-click “Command Prompt” and select “Run as administrator” to open an elevated command prompt. In the command prompt window, type without quotes “sfc /scannow” then hit Enter. When it is finished, restart the computer and try installing the Windows Update again.

If the problem continues, download the System Update Readiness Tool to fix the corruption on your operating system.
