This has been going on since mid-August. I've gone through Troubleshooting with no success. My OS is Windows 7. The only updates that have successfully installed are Definition Update for Windows Defender, Windows Malicious Software Removal Tool, Security Update for MS .NET Framework 4, and various updates for MS Office 2007 suites and individual Office programs, (I know I should have dealt with this sooner! Unfortunately, it took me a while to realize this was happening.)
Windows Update successfully downloads the updates and begins the installation process. When I restart the computer to allow the updates to finish being installed, it begins configuring, then shows an error message saying configuration failed. At that point, it reverses the changes it had begun to make.
Any suggestions as to how to fix this problem would be greatly appreciated. Thank you!
