Question

I’m getting Error 0x80070490 when I try to install updates.  What do I do?

Answer

This error might occur if you have a corrupted file in the Component Based Servicing (CBS) manifest. To resolve this, you will need to perform a repair installation.

Performing a repair installation will restore the current Windows installation to the version of the installation DVD. This also requires the installation of all updates that are not included on the installation DVD.

Note: Performing a repair installation will not damage files and programs that are currently installed on your computer.

To perform a repair installation of Windows 7, follow these steps:

1. Close all programs, and then restart the computer.
2. Insert the Windows 7 DVD in the computer's DVD drive.
3. In the Setup window, click Install Now.
   

Note If Windows does not automatically detect the DVD, follow these steps:

1. Click the StartCollapse this imageExpand this image button, and then type Drive:\setup.exe in the search box.
         Note The Drive placeholder is the drive letter of the computer's DVD drive.
2. In the Programs list, click Setup.exe.
3. In the Setup window, click Install Now.
4. Click Go online to obtain the latest updates for installation (recommended).
5. Click Yes to accept the Microsoft Software License Terms.
6. On the Which kind of installation do you want? screen, click Upgrade.

When the installation is complete, restart your computer, and then try to install the updates.
