Note: You must print the subtree in order to determine which certs to delete.
Note: Microsoft has this to say with respect to editing the Registry on any PC:
"Warning: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Regedt32.exe. Note that you should back up the registry before you edit it."
Using Cert Manager to delete keys/certs from MSIE/Outlook:
It is easier to use MS Cert Manager to delete certificates from IE's certificate database. This tool (certmgr.exe) is obtainable from Microsoft's website, unfortunately packaged inside the Java Development Kit: http://www.microsoft.com/java/download/dl_sdk40.htm
Additional documentation on Certmgr can be found at: http://support.microsoft.com/support/kb/articles/q167/8/37.asp?FR=0
(This is an article about the Internet Client SDK but documents Certmgr adequately.)
