Norton SystemWorks Not Cleaning Items

Can anyone tell why when I run the One Button Checkup in norton systemworks NOT all problems are cleared in the windows system registry scan and the norton cleanup scan?

 

I have 12 items in the system registry and 142 in the cleanup scan that systemworks will not clear.  I am using windows Vista-Home Edition operating system.  The detail for system registry scan says WRP protected.  In the norton cleanup scan there are 6 items in temporary files and 130 in cached files that will not clean.

 

Does anyone have any suggestions.  This has been going on for some time.
