    Hello all,
    How to know whether our machine is 32-bit or 64-bit..this 32 or 64-bit depends on OS or hardware?..

    Both

    Well if you go into my system in control panel it will tell you if your running a 64 bit OS.

    Most CPUs these days will run either a 32bit or 64bit OS.

    x86 CPUs will only run a 32 bit operating system but most CPUs these days are reffered to as x86-64 or x64 meaning they will run either a 32 bit or 64 bit OS.

    So a core 2 duo/quad will run a 32 or 64 bit OS whilst the initial pentium 4 CPUs would only run a 32 bit OS however these were upgraded to be able to handle a 64 bit OS later on.

    actually if we type msinfo32 and if we look at the system type , we can know the h/w..but we are typing msinfo32 which means we are retrieving the details for 32-bit?

    No it means you are running an application called msinfo32, you can still run 32bit apps in a 64bit OS but you can't run 64bit apps in a 32bit OS.

    msinfo32 is just an application based within windows. it will tell you wether you have a 64bit or 32bit os. The name msinfo32 does not mean it will only give you info if you have a 32 bit cpu.

    Right click "My Computer", then properties - it'll tell you there.

    Yes, it depends on both. You can't install a 64bit OS on a 32bit CPU unless it has 64-bit extension. And if you install a 32bit OS on 64bit hardware, then the OS will still be 32bit.

    See here from more information.

    On windows 7 it does bring up a GUI even if run from the command prompt. It doesn't seem to run at all from the command prompt on Win xp. Microsoft says you can run it with switches from the prompt on win 7 but it doesn't seem to work. Interesting only ever tried to run it the one way.

    From the CLI (Command Line Interface), type in: systeminfo (pre-XP, the cmd is: cmdinfo)

    Alot of information will be displayed, however the two bits of info that you will find your requried information will be under:

    OS Version this will tell you the OS

    &

    System type this will tell you if your system is 32bit or 64bit

    Oh nice I know I've read about that tool before but had forgotten about it. I'll have to remember it this time that gives some handy information in one spot.
