Windows optimization applied etc. skipped

I have Norton Utilities 16 on Windows7. It has worked fine for a year, but about 2 weeks ago I got messages that the 1-click optimization skipped several tasks, such as: - Windows optimization - Unused Application found - Disk defragmentation and the System health remained LOW and recommended the same tasks that was just completed. These tasks are enabled under SETTINGS. Reinstalling the product did not fix the problem. The new Norton Utilities program I purchased (which is the same version as the old one) in a bundle with the current Norton IS also did not fix the problem. It seems that some other program disables Norton Utilities.

My NU version is 16.0.1.7. on Windows7.  It worked for about a year.  Now it does not improve my System Health at all and recommends the same tasks, that were just completed.  I installed a new copy of NU which was bundled with my new NIS, same result.  All of these tasks are enabled on the Settings of the 1-click optimization.  Smart Update says: Your product is up to date!
