reg scan has problem at hkey_classes_root\cdo.knowledge entries. It times out at that point.

attempts to scan my registry result in a timeout at entries involving hkey_classes_root\cdo.knowledgeserver.1

 

and now cdo.knowledgestartaddress\curver

 

Ran scan in safe mode and apparently corrected the first as scan stopped at the second
