i had the same problem. Install 2 just stopped installing; cpu usage went to
100% and all programs slowed. I quit all programs but update still did not
finish installing. After forced restart - automatic update shows no updates
needed and "Review your update history" online, it shows this portion failed
- but the "Failed Icon" one is supposed to click to learn how to resolve the
problem does not link to any web pages. How sad to see no resolutions here
either....
