When I have a pagefile configured I can see it in windows explorer on the C: drive, I can no longer see or find any pagefile on any drive which would indicate there's no actual physical pagefile on the disk so where is windows 7 hard-faulting its pages from?

I ran quite a few memory hungry programs (I have 8gb RAM), and when COMMIT showed 6/8 I got the "windows is low on memory" warning.
I gave windows a 4GB pagefile and tried again. COMMIT is now showing 2/11 (GB) and I can easily load up a lot more memory hungry programs than last time before getting the "low on memory" warning..
so is HARD FAULT really meaning hits to the pagefile, or just hits to the hdd to get program data?
I believe it's just to the hdd.
I rarely use more than one menory hungry program at a time (eg: games, video editing etc) so I feel happy in ditching my pagefile for good, especially when I have an additional 8gb of physical RAM being delivered in a few days (unless somebody can give a good reason for keeping a pagefile?)

They used to call it a page-fault, but now its hard-fault. Now I see in your quote the term 'hard-page-fault'. Are they the same things?
When I used to work on mainframes they used 'swap-files' as a cheap alternative to physical memory. When processor time is critical for clearing transaction queues then using slow-speed hard-drive swap-files is something you try and avoid where possible (using real-time priorities). If we could afford to have all physical memory then that's what we'd have done (though a finacially stupid idea for low-priority batch applications). In this day of cheap physical memory and relatively low usage I cant see a single reason for using page-files - unless modern OS' have some unaddressed legacy requirement for having one...
