That would be a backward step from earlier Windows versions I just can't see MS making. Granted the contents may be lost, but they're constantly changing anyway and some is in RAM so automatically lost on powerdown.
Win reserves a minimum size paging file initially based on your RAM size but adjusted to suit your system's PF usage history, and increases it if necessary. If you want to really ensure the pf doesn't ever get fragmented, track your pf usage under worst-case conditions and set your own minimum to a higher value. But I strongly advise leaving the maximum open or at a ridiculously high value (say 20Gb) to avoid any possible hiccups.
With two physical drives it may help performance to set up a paging file on each; Win will use the most convenient at the time. I have 3Gb minimums on C: (the Win partition) and F: (the second drive).
Insufficiently large paging files on the other hand, will hinder the performance of Windows Vista, which uses a technology called SuperFetch to store boot information, Graphic User Interface (GUI) data, and other essentials in the paging file(s) between work sessions. It has been found that an overly small paging file can also cause GUI mishaps, especially at higher screen resolutions.
