How to check if Windows 32 or 64 bit?

There are multiple ways to check whether a Windows computer is running 32-bit OS or of 64-bit one.

Check 32 or 64 bit using WMIC

You can get to know the OS architecture by running the below simple command.

wmic os get OSArchitecture

Example:

c:\>wmic os get OSArchitecture
OSArchitecture
64-bit
c:\>

Using program files folder:

If you have a separate program files folder for x86 applications(named Program Files(x86) ) then we can infer that you are running X64 Windows on your computer.

Few things to note:

  • You can run X64 based Windows OS only on 64-bit computer. If your computer is of 32-bit then the software(Windows OS or any other applications) running on your computer must be of 32-bit only.
  • If your computer is of 64-bit, then it does NOT mean that you have 64-bit OS. You can run either 32-bit OS or 64-bit OS on a 64-bit computer.
  • Even if you are running 64-bit OS, you can still install 32-bit applications on your computer.  All the 32-bit applications are installed to a separate folder named “C:\Programs Files(x86)“.

    What is the equivalent of msinfo32 for 64-bit Windows ?

      There’s no separate msinfo32 for 64bit windows. The same command works in both 32 bit and 64 bit windows.

    betterway:

    echo %PROCESSOR_ARCHITECTURE%

      That’s not actually a better way. The %PROCESSOR_ARCHITECTURE% environment variable is based upon whether or not you are running a 32 or 64 bit process. For instance if you start the command prompt from the system32 directory on a 64-bit OS the variable will return “AMD64”. However if you start the command prompt from the SysWOW64 directory that variable will return “x86.” Both of these command prompts return “64-bit” when you query WMI. So the WMIC result is actually a more accurate tool for detecting a 64-bit OS.
