I have a Windows 7 computer. This morning it tried to do my regularly scheduled updates (14 of them), and when it got to update 7 it hung up. The dots were moving, so it appeared to be progressing, but after a half hour it was still on #7. I hard rebooted, and when I went to Windows Update there was an error message that an update failed. The next reboot restarted the update process, but then it hung on update 8 in the same way. What can I do to fix this? I ran both Norton Utilities and Malwarebytes to make sure it was clean, and there were no problems.
