What can you do if the Windows 7 Service Pack 1 Update fails? The answer depends largely on the error code that you get directly on the screen or in the Windows event log.
Regardless of that code, it is still possible to try two generic fixes before you try to find a solution for the specific error messages.
The first thing that you may want to try is running the Windows Troubleshooter to resolve any problems that prevent Windows Update from working properly.
Windows 7 users find the troubleshooter when they click on the Start orb, select Control Panel > Troubleshooting and there the Fix problems with Windows Update link.
The Windows Update troubleshooter "resolves problems that prevent you from updating Windows", which basically means that it tries to repair Windows Update if it is broken or not working properly.
A click on Next starts a scan that should take less than 30 seconds to complete. Problems and issues that have been found are automatically repaired by the troubleshooting process. The troubleshooting tool displays problems that have been found during the scan and if it was able to resolve the problems.
It is then suggested to try the Windows 7 Update again via Windows Update to see if the troubleshooter corrected the updating issue. If the update fails again it is time for the second option, the System Update Readiness Tool for Windows.
Make sure you download the tool that is compatible with your operating system. This means that you need to select the 32-bit or 64-bit edition based on your operating system and the correct language the tool is offered in.
This tool is being offered because an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software.
The software has a size of roughly 100 Megabytes for 32-bit systems and 300 Megabytes for 64-bit systems.
What does it do?
After you download the System Update Readiness Tool, it runs a onetime scan for inconsistencies that might prevent future servicing operations. This scan typically takes less than 15 minutes to run. However, the tool might take significantly longer on some computers. The Windows Update progress bar is not updated during the scan, and progress seems to stop at 60% complete for some time. This behavior is expected. The scan is still running and you should not cancel the update.
The tool verifies the integrity of several Windows Registry keys
Files that are located under the following directories:
Registry data that is located under the following registry subkeys:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing
Which errors can it repair and fix?
Try to install the Windows 7 Service Pack or another Windows Update again after the System Readiness tool has finished its scan.
