Windows 7 SP1 Update Problem


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.
