    [QUESTION] Installed x32 on my laptop, but it supports x64


    I installed Windows 8 x32 on my laptop. It has 3 GB RAM and the processor is x64-based. I don't use my laptop for much other than e-mail, Facebook, YouTube. Here are my questions:


    Is there any point to switch from x32 to x64?


    Is there any down side? I read somewhere that I won't be able to run 16-bit applications (I don't even know if they still exist)?


    Do I need to do a clean install, or can I use the Upgrade install option rather than the Custom (advanced) install option?

    You will need to do a clean install to switch to x64.

    With what you are using the Laptop for, there's no point to upgrade to X64 bit. Most applications are still in 32 bit and with 3GB of RAM, there's is no advantage using X64.

    I have x64 on 1.5 GB ram. No problems.

    Then you can stay with x32.

    Is there any point to switch from x32 to x64?
    Yes. Large memory support (above 4GB ram) and increased programs performance (1-10% depending of task).
    Better security in Win64: kernel protection, UEFI, secure boot...

    Is there any down side? I read somewhere that I won't be able to run 16-bit applications (I don't even know if they still exist)?
    16bit will still be possible if you use DosBox.
    And there are many virtualisation solutions like VirtualBox, VMware, Parellells, built-in Hyper-V (Win8 pro) where you can run any operating system side by side and any older program in its own window.

    The real small downside on x64 is that each program (even some 32bit ones) use more ram memory; it can be considered a downside only if you run out of memory. I can live with 1.5GB ram only on x64 for internet usage only: all is OK. Depends what you run at the same time.

    Give x64 a try if you are interested. The programs will work normally.

    Is there a down side?, apart from the aforementioned lack of support for 16-bit applications - x64 files are a little larger than x86 32-bit files, so your windows install disk goes up from about 2.5 GB (x86) to 3.5 GB (x64) - when you consider the amount of reduplicated redundancy in a windows installation, and the implication of using 64-bit applications instead of 32-bit, as your installation matures, you may be looking at 1.5 times as much disk space needed for x64 than for x86. Still, hard disk sizes are increasing far beyond limits thought impossible 20 years ago, when we dreamed of being able to afford 500 Mb hard disks to put our Windows 3.11 systems on.

    On the other hand, there is no likelihood that computing will ever embrace 128-bit mainstream operating systems (64-bit supercomputing still seems to be enough even for the most demanding boffins today, as it has been for many years) so 64-bit Windows is here to stay, and it runs 32-bit applications perfectly well, you might be best sticking with the present and future, rather than the present and past.

    Good point.

    Yeah, I forgot the HDD space. I don't even feel the difference because storage space is big enough.

    The so called lack of 16 bit can be easily compensated:
    You can add 16bit support by yourself using DosBox or VM's, seems like many people don't know about this yet.
