There are several reasons why you might receive the Windows Update failed error message or the error “Some updates could not be installed.” Another common error related to Windows Update is Windows trying to install the same update over and over each time you restart your computer. This could simply mean the update didn’t install correctly, or it could mean you have malicious software on your computer that has interfered with the update. To troubleshoot Windows Update errors try the following:
Check The Status of Windows Update
You can see if the update actually installed or not by visiting the Windows Update website. You can do this easily by clicking on the Start menu in Windows. Look for “Windows Update” in the menu. Once the website loads, look to the left for “Review Your Update History.” You will see the latest updates that were downloaded and the status of those installations. All updates should be in green. If you see any that are in red, click the link and copy the update’s number (such as KB975561). Another Window will open the troubleshooter. Click on “Find Solutions” and search for the update number that failed.
If the troubleshooter does not give you any options, you can try uninstalling the update in the Control Panel under Add / Remove Programs. You may need to tick the box that says “Show Updates.” Be sure to backup before you do this.
You can also install the System Update Readiness Tool for Windows Vista and Windows 7. Once this is installed, you should be able to run Windows Update without a problem.
Scan For Malware If Windows Update Fails
A virus’ first order of business is usually to disable your security and prevent you from running updates. Failed Windows Updates may result in a virus infection. To scan for malware, reboot the computer and enter Safe Mode. To do this, boot the PC and start tapping the F8 key. Select the option for Safe Mode With Networking. Once Windows loads, open your web browser and go to http://malwarebytes.org and download the free version of Malwarebytes. Run a full scan and remove anything it finds.
If you continue to have issues with a Windows Update, visit the Microsoft Support site and search for a fix. Be sure to have the number of the failed update and include it in the search.
