I recently restored an Acronis image file, and then the system was busy "checking for updates", and never would download the updates to install. The CPU activity was constantly between 25% and 50%.

There is LOTS of discussion about this problem on various web sites. This post pointed me to the solution.

I downloaded the KB3161608 update and manually ran the install. It installed fairly quickly, then I rebooted and checked for updates. This time it had no problems downloading and installing.

UPDATE 12/2016

Microsoft broke my Windows updates again. This time I used the first solution mentioned at the Windows Secrets forums.

If that isn't successful, there is a second solution. This has extra manual work to stop, and then start various Windows services.
