    CHANGED PAGE FILE SIZE good or bad

    I am running windows 8.1 on my laptop which has a 128 gb SSD and I have freed up some space on my C Drive by changing my pagefile from 12gbs to 2000 --4000 . I have a 12 gb ram and dont use the laptop much, no games or that sort of thing. Have I done a bad thing. I googled it and saw this...........................If your system is configured for crash dumps you'll need to have a larger pagefile or Windows won't be able to write out the process memory in the event of a crash—though it's not very useful for most end-users............I have no clue what this means or if it applys to me.
    So what I would like to know is 2000-4000 mbs ok for pagefile for a light user.
    Should I look futher into the------ If your system is configured for crash dumps----THANKS

    I would let Windows manage the page file size for you.

    Reducing the page file if you have plenty of RAM is a good solution for freeing disk space. If you don't have sufficient RAM it is a bad idea as Windows will be very slow paging back and forth and may even crash.

    Mark Russinovich from Sysinternals wrote an excellent article on page file sizing, and the myths that surround how size should be calculated...

    http://blogs.technet.com/b/markrussi...7/3155406.aspx

    The section "How Big Should I Make the Paging File?" gets into the specifics, but the entire article is an informative read.

    The 2008 Russinovich article is bordering on grossly outdated information. (the Windows XP era)

    Try this instead; https://support.microsoft.com/en-us/kb/2860880

    PF in a modern memory rich system is all about the Crash Dump, and very little to do with any performance gains.

    2-4GB is more than enough as a max PF size on a stable system. (probably too much based on the OP's usage and hardware spec)

    If your computer is stable you don't need to consider the memory dump until you actually have a crash, then you can reset it after a crash
    so that the crash dump information can be properly compiled upon next system crash.

    W7 has a patch available to allow creation of crash dump files without a page file, it's possible that it's baked in to W8+ (early discussion here).

    Russinovich basically said that the page file size or the need for one at all boiled down to how you use the computer.

    Most users do need one, MS Office components generally use it by default.

    Usually the first sign that a page file is really needed or is too small, is the program requesting it crashes instantly - it disappears, along with your work/changes that hadn't been saved

    For a quick check on current page file usage, scroll down this page to #34, wmic pagefile, I use the text output method.

    FWIW, my W8.1 box with 8GB RAM has automatic page file management and a 1.2GB page file.

    cheers, Paul
