While I was away for three days, I cleaned my Vista HP SP1 notebook with v.1.8.0.466 Registry Cleaner. With only the ActiveX... scan selected, it found the same items posted by siliconman01, but could not delete them. Permissions show that only "Trusted Installer" has full control.
I put HeaderFooter.HeaderFooter in the Ignore tab -- guess I'll leave it there for v.1.8.0.467 ...
