I know nothing about the windows kernel. If windows has back up virtual memory in the form of a file i dont know either but i think it is referring to 'kernel memory' in the task manager. In the pic below you can see that is not a lot and thus doesnt have to do with pagefile.sys. All i know is that if you turn off the pagefile, the file 'pagefile.sys' (which is hidden btw) no longer exists in the root directory where windows is installed. Without the file, you will get the message that there is not enough memory when opening lots of memory intensive apps. You can verify in the task manager if you still have a pagefile under 'page file usage' i believe.
In the virtual memory window i see under 'paging file size (MB)' the set size of my pagefile limited to my c:\ drive. I read somewhere that it is better to have only 1 pagefile instead of several on each partition / drive.
Well that is all i know. It used to be a big deal for me because my old computer had a harddrive that would only run in PIO mode, so i turned off the pagefile and programmes would load much faster (no disk swapping) but i also ran out of memory quickly as i explained in my previous post.
