In short, as stated here before, there isn't any point in having an excessively large page file. Considering the fact that you are here, asking about this, I would assume that your level of expertise would exclude any need to have a memory dump in case of a crash. I may be wrong, and I don't mean to insult or sound brash, but I am just guessing that a memory dump would't be anything you would need. I also saw a listing of hardware specs under your first post, which listed 2x1gig of ram. If that is the system you are speaking about, I would recommend no more than about 1gig of page file. Unlike linux swap files, windows doesn't use its page file to store hibernation data, it uses a seperate hibernation file, so you dont need to have a page file larger than ram. If you have 2 gigs of ram, the page file will never get used, and if it does, it would only be due to a program having a memory leak, and in that case, your system will likely be on its way to crashing or at least needing rebooted, and that program not getting ran until the memory leak gets fixed. Just leave the page file alone, and if you have already changed it, change it to something reasonable like 768-1536mb or so, more will have absolutely no benefit and possibly be detrimental.
