Windows 7: Random BSODs, 100% Utilization, and Driver Issues

Windows 7 Home Premium 64-bit SP1


There was a driver from "New Software, Inc." for a product called "Folder-Lock", which is used to be able to assign a password to access windows folders, that was getting invoked by the Win7 System Kernel. I uninstalled this product, and presto, problem gone - no more 50% of CPU being used by system - - -

How I Did It::

However, Windows Process Explorer does display info for all the Drivers being loaded/invoked for a given process - including the "System" kernel process.

So I just went and slowly browsed thru all 173 of them, and thought about what non-Microsoft drivers might possibly have something to do with locking up resources - a clue given to me by the Starting Address for the offending TID from Process Explorer:
