    32 bit or 64 bit Windows usage case

    Given : 1-2 Gb RAM , 64 bit CPU
    In terms of performance will 32 or 64 bit edition of Windows will run faster on such machine assuming we use only corresponding "bitness" software there?

    Depends on the use cases. But if you have enough memory, and run x64 applications, x64 would be faster. If not, x86.

    use case : I have 1-2Gb RAM 64bit CPU and i want to use MSOffice, file copy deleting operations, browsing with IE - such general use.
    So what will be faster on such machine 32 bit Win or 64, considering such amount of memory.

    i will perfer 32-bit. the ram will be most important resource for you, and 32-bit software use less memory

    Agree. Only for Office, x64 would be better. But IE, like Chrome and other modern browsers, eat lot of memory, and so the lower consumption in an x86 OS, and its applications, will make it faster.

    None of the programs in the user case is really CPU heavy. I don't think you will feel any big difference between running one or the other bit version of the same OS

    what if I have 4GB RAM? 32 or 64 + subquestion - will I benefit from NTFS compression with 1,2,4 GB RAM?

    64-bit more has several minor advantages: 64-bit programs are 10% faster at average and can use any amount of virtual memory allocated in single contiguous space, and one major disadvantage - 64-bit code tends to use more memory, so swapping has more chances to occur. so if you are short on ram, 32-bit OS is prefered. if your programs are tiny, you may prefer 64-bit OS even on 1 GB system. AFAIK, 32-bit Wndows cannot use more than 3.5 GB of RAM, so for 4 GB system 64-bit Windows + 32-bit application programs should be optimal.

    I would definitely go with 64bit if you are using more than 2gb of memory. a single process in win32 can only use 2GB ( some exceptions apply)
    example: 7-z will not be able to use big dictionary. but we have srep for that then

    NTFS compression does not require high memory amounts. It will depend on how frequently you will need to access those files.

    FYI, if you choose 64-bit Windows, you will still be running 32-bit Office by default. You may also be running 32-bit IE 11 by default. There is a 64-bit version of Office, but you have to go into the MS website and select it – they never give it to you by default. Also, to run IE 11 in 64-bit mode, including Enhanced Protected Mode, you need to go into Internet Options, Advanced and check the right boxes. Then it will run using 64-bit ASLR, which is good for security hardening.
