Computer 32 bit or 64 bit?

I regularly see software advertised for 32 bit or 64 bit systems. How do I check which mine is running please? I am running Windows 7.

What does this actually refer to? Does this mean I can only run specific software on my computer?

Confused......

    32 bit based systems have a limit of only being able to address just over 3Gb of memory. 64 bit systems go way beyond that. Only software specifically written for 64 bit environments will truly benefit from running in one. There was a problem with hardware drivers not being available for 64 bit operating systems, but that is largely dealt with now. It just makes older hardware obsolete even faster!

  • Thanks. I have discovered I have a 64 bit system, so at least now I know which software to buy ;)

    Microsoft recommends at present that you install 32-bit versions of Office on 64-bit Windows...

    The reasoning being due to plug-in compatibility

    Can't expect Microsoft to produce an Office suite that's actually compatible with its own operating system, can we now?:)

    64-bit is the way forward (and most other operating systems are already 64-bit).

    But right now for Windows, 64-bit only offers advantages over 32-bit in certain circumstances for home users, for instance (a) if you need more than 3.5 GB memory, (b) if you have a 64-bit application.

    It isn't going to help playing movies, surfing the web, reading email, doing word processing, etc.

    I have found a need for 64-bit Windows once, where I wanted to run a virtual machine of a 64-bit OS.

    It is compatible, it's third party addons and other solutions that have been developed for 32 bit environments (which up until Office 2010 was the only platform available) that are incompatible under the 64 bit versions. Hardly the fault of Microsoft.

    And massve improvements in security than the 32bit counterparts.
