Every time you use Windows Update or Microsoft Update to install updates on your computer, you may encounter some errors in the process.
One is the 80070490 error, which occurs if the Component-Based Services (CBS) manifest damaged.
Solution 1: Use System File Checker to repair damaged Windows files

Here’s how to do it:
- Click Start
- Go to the search field box and type CMD
- Select Command Prompt
- right-click and select Run as Administrator
- Type sfc / scannow
- press enter
- Restart your PC and try to install the update again.

Solution 2: Run the System Update Readiness tool
If you still can not fix the error 80070490 after the SFC scan, use the System Update Readiness tool to fix Windows corruption errors and install a Windows update or service pack again.
This tool is used due to the Windows servicing store’s inconsistencies, which may prevent the successful installation of future updates, service packs, and software.
It checks your computer for inconsistencies and tries to resolve such issues if found.
Download the System Update Readiness tool by clicking on the download link that corresponds to Windows’s version running on your computer. This tool is regularly updated, so always download the latest version (check if your computer is running 32 or 64-bit Windows).

- In the box Windows Update Standalone Installer dialog, click Yes. This tool runs automatically for about 15 minutes or more, so it does not click Cancel.
