64 bit and 32 bit?

    64 bit and 32 bit?


    under PC info it says I have the 32 bit windows 8 OS.

    I didn't know there was a 64 bit or 32 bit, because when I bought/downloaded windows 8 online from windows own website, it never gave me an option to choose between 64 or 32. I just bought it for about $67...

    so obviously I bought the 32 bit version and I guess there's no way of getting the 64 bit without making another purchase? there's a program I want to use that only works on 64 bit.. this is my fault, I guess.

    You can go to PC Info, or as it's called System Info to find out for sure. Go to the Desktop, and pull up the sidebar Charms--Settings--PC Info. Or you can just type system info at the Start Screen and hit the Settings filter and click that.

    If you've already rated your PC's hardware, you should see a link that says View and print detailed performance and system information. This will open a new window, and under the System subsection, you should see if your CPU is 64 bit capable. If it doesn't, then most likely you have a 32 bit only processor.

    I'm guessing you did the upgrade, which most likely just upgraded your existing 32 bit previous Windows version.

    If you upgrade from a 32 bit OS, it will install a 32 bit OS. This is because Windows cannot perform an upgrade from 32 to 64 bit, it must be a clean install.

    yes, that's exactly what I did. I went from 32 XP to 32 8.

    /sigh

    .
    it says i have a x64 based processor, so that means it's 64 capable, i imagine.

    but it looks like i just blew 60 bucks by mistake.

    Giroux, the difference between 32/64 bit is how much ram can be accessed (32bit = Max of 3gb). If your PC has more than 3GB or can be upgraded above 3GB then 64bit may be for you. There are "quirks" still with 64bit OS and applications which are 32bit.

    Fortunately those issues are fading fast and most apps, even if 32bit only will behave properly on 64bit and in fact, sometimes perform better on 64 than 32 and even preferable to use under 64bit. One fine example of that is MySQL which seems to perform better in 32bit mode on a 64bit OS.

    With the $40 upgrade you can get both the 32 and 64 bit versions for the same key. To get the 32 bit you have to be running a 32 bit OS and to get the 64 bit you have to be running a 64 bit OS. I presume the same is true for the $67 version.

    You will need to do a clean install with 64bit.
    But you'll lose all your programs.

    I think you're allowed to use the key again on a clean install of the 64bit on the same pc.

    But you need a new ISO file or DVD with the 64bit version.

    There's no reason to be using 32-bit OS on a machine with 4GB or more RAM. Don't listen to anyone who tells you that 64-bit will slow down your 32-bit applications. If a 32-bit application doesn't work, it's probably because Windows 8 broke it, not because 64-bit broke it. 64-bit Windows is fully supported by modern software and hardware (past around 2007-2008 at least, when vista 64-bit became common). Also, if you can get a 64-bit Windows 8 ISO of the same version you upgraded to, you can use your Windows 8 product key in a fresh reinstall of the 64-bit version and it should work just fine. The license is NOT tied to whether it's 32-bit or 64-bit, JUST if it's 'core' or 'pro' and whatnot.

    So you didn't waste your money, just find your windows 8 edition in a 64-bit ISO and do a wipe/fresh-reinstall of your OS.
