Gary, let's go back to basics.
The pagefile is an 'extension' of your RAM. Whenever you run short of RAM and there is a request by a program for RAM, Superfetch will page-out the lowest priority (the one that has not been used for the longest time) part of the occupied RAM in order to make room for the new request. Now that could be anything that happens to linger around in RAM at this point in time.
The good news is that with our modern PCs that have 4GB or more of RAM, chances are slim that anything gets paged out at any time. The page requests (hard faults) that you may see e.g. in the Resource Monitor are mostly fake paging requests. Those occur because Superfetch uses the paging mechanism to populate RAM without really populating the page file.
