Hello, I recently tried to update my Windows 7 Service Pack 1 (KB976932) and I’m stuck with an error code. The code is 0x80070490.
Could you please guide me on solving this issue? Thanks in advance.
Hi, I am here to assist you solving this issue .Please refer the following guide given below :
1. Firstly, please download and execute the System Update Readiness Tool (Checksur.exe). This tool will run a one-time. Scan for any freak behaviors which might prohibit servicing operations.
Note : System Update Readiness Tool validates the integrity of a few directory files and registry subkeys in your system. Normally, it will take less than 15 minutes to complete the scan , yet it depends on the system environment.
If you have not had this tool yet, please click the following link given below to get it.
All supported x86-based version of Windows 7 :

All supported x64-based version of Windows 7:

2. After the scan has completely finished, please try installing the updates again.
According to Microsoft support, 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 system file checker 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. If it prompts you to insert the Windows 7 setup disc, insert the disc on your optical drive and continue. When it is finished, restart the computer and try to install the update again.
In your case, since you are updating your operating system to Service Pack 1, run the Windows 7 Service Pack 1 update installer again. If the problem continues, download the System Update Readiness Tool to fix the corruption on your operating system.
