Adding a killbit for a control that Nessus says requires one.

In brief you need to find or create the classid in:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility

However, on one I found I first had to hunt the name in HKEY_CLASSES_ROOT\CLSID

eg. Nessus reported

  Class Identifier  : {D63891F1-E026-11D3-A6C3-005004055C6C}
  Filename          : C:\Program Files (x86)\xxxx\Runtime\NCSECW.DLL
  Installed version :

But when I search for NCSECW.DLL I got a different Class ID and that was what I needed to use to add a killbit for.
