WindowsUpdate_8024800A" "WindowsUpdate_dt000

Windows could not check for updates automatically. Never happened before, this PC was inactive since Dec 24th, but has always worked prior to this error. Note, a java update was installed, the McAfee free install box was unchecked to prevent installation of that unwanted (please stop this, Oracle) program.
