Incomplete Windows updates can cause errors on your computer. However, you can remove these updates in the Windows Control Panel. After you uninstall the incomplete installation, you can attempt to reinstall the update or leave the computer without the updated operating system. The Windows uninstall wizard provides you with help to remove the update, so you can eliminate errors associated with the updated files.
Click the Windows "Start" button and select "Control Panel" to open the main utility window. Click the "Program" link.
Click the link labelled "Programs and Features." A list of currently installed programs is shown. Click the option labelled "View installed updates" to view Windows updates.
Click the incomplete update you want to remove. Click "Uninstall" at the top of the window. Click "Yes" to confirm that you want to remove the software. Reboot the computer when the uninstall process completes.
