    How do I get some information about the machine my program runs on?

    Is there an easy way, using the standard libraries or win32 api to get basic system information, for example, the CPU speed, the graphics card capabilities, the amount of ram and the screen refresh rate?

    You almost certainly will have to use different API's for each of those types of information.

    Some of it can be found here:
    GetSystemInfo
    http://msdn.microsoft.com/en-us/libr...81(VS.85).aspx
    SYSTEM_INFO struct.
    http://msdn.microsoft.com/en-us/libr...58(VS.85).aspx

    GetDeviceCaps
    http://msdn.microsoft.com/en-us/libr...66(VS.85).aspx

    That will probably give you MOST of the info you where asking for.

    To get the name of the processor, you can use CPUID to get the name string from the processor. I'm not sure if Windows supplies an interface to do that - but it's easily done in a little bit of inline assembler.

    You can also look at WMI:
