How can you tell if your system is 64 bit or 32 bit?

Answer 1

Go to:

My Computer > Properties > Advanced > Environment Variables > System Variables > Processor_Architecture

x86 is 32-Bit

x64 is 64-Bit

On Windows 7 and Windows Vista, right click Computer from the desktop and it will open up a window. In it, it will directly tell what type of computer you have.

If you are on a non-Windows machine, open up a terminal, and type:

uname -m

Any output similar to 'i586' or 'i686' means a 32-bit Operating system. Anything that looks similar to 'x86_64' or 'x64' or 'emt64' means a 64-bit Operating System.

All of this refers to the Operating System you are running. However, this does necessarily tell you anything about the Hardware you have. It is entirely possible to run a 32-bit OS on 64-bit Hardware (though, the reverse is not possible).

Answer 2

Assuming this is a windows machine; if you right click My Computer (or Computer under Windows Vista) and select properties, you will get a dialog box showing the specification of your machine. There are two things to look at here:

* The name of the processor; search for the processor name with a search engine, and you will find out if it capable of running in 64 bit mode. * The operating system type will also be listed, including whether it is a 32 or 64 bit version.

Answer 3

first a 32bit OS accesses the hard drive in 2gb chunks were as a 64bit OS can do 9gb and up as a single unit lessening the load on the prossessor.

64bit OS's use alot more ram as it looks at the entire application running not just pieces of it. but the reward is the program will run faster.

Answer 4

Push your windows key and the Pause/Break key at the same time, this should pop up a window on all Microsoft operating systems. On Windows Vista/7 there will be a title saying System Type: and it will tell you if it is 64 or 32bit.

On XP do the same thing, but under System the operating system name will have x64 after it if it is 64bit, if it doesn't have any mention of x64 then it is 32bit :)

Another way is to go to your Control Panel, Click "System," and it will be listed on the main tab under "system type." You can also access this "System" or "System properties" panel in a number of other ways - there's a link to it in the Explorer menu bar when you view your "Computer" in Vista. Alternatively, you can open a command prompt by clicking "Run" in your Start Menu, then typing "cmd.exe" or "cmd," (or just type directly into the search bar in Vista's Start menu), and then typing "msinfo32.exe."

Answer 5

You will need to look in the BIOS or find out what type of CPU (MicroProcessor) you have.

You can't really rely on looking at the properties of the Operating System, because you can install a 32 bit OS on a 64 bit computer, (I know from experience) but you can not install a 64 bit OS on a 32 bit computer.

Answer 6

There's a program called Unity which I've used to check whether my computer can run something, but the whole process was run by the webpage I was downloading the beta from. Try searching for Unity on the internet?

Answer 7

In windows, right click on "My Computer" then left click "Properties", then you can find your system type: 32-bit or 64-bit.

Answer 8

It's very easy follow instruction:-

open control panel->System and security->system

OR

my computer->right click->properties

you'll get all the details.
