Or maybe they count on the bungling update as a lucky charm of sorts.
One user noted, This installs successfully.
But I happened to see that it appeared to be updating again.
If it was successful, why does it do this?
Another user noted on the forum, My error is slightly different.
Windows update shows KB3119142 to have successfully installed on 13/01/2016 but that installation failed on 15/01/2016.
It is not listed in Control Panel | Programs and Features | View Installed Updates.
Windows update was hanging at 0% downloaded.
As usual, Microsoft is yet to comment on the bug that is causing this update reinstallation problem.
