How can I find out whether my Windows is 32 bit or 64 bit?


How can I find out whether my install of Windows (specifically XP and Vista) is either 32 or 64 bit?


Additionally, how can I find out if my hardware will support a 64-bit operating system?



Answer



Windows Vista


If you have Windows Vista, there are two methods to determine whether you are running a 32-bit or a 64-bit version. If one does not work, try the other.


Method 1: View System window in Control Panel

  2. The operating system is displayed as follows:

    • For a 64-bit version operating system: 64-bit Operating System appears for the System type under System.

    • For a 32-bit version operating system: 32-bit Operating System appears for the System type under System.




Method 2: View System Information window



  1. Click Start Collapse this imageExpand this image Start button , type system in the Start Search box, and then click System Information in the Programs list.

  2. When System Summary is selected in the navigation pane, the operating system is displayed as follows:

    • For a 64-bit version operating system: x64-based PC appears for the System type under Item.

    • For a 32-bit version operating system: x86-based PC appears for the System type under Item.




Windows XP


If you have Windows XP, there are two methods to determine whether you are running a 32-bit or a 64-bit version.


Method 1: System Manager



  1. Click Start, and then click Run.

  2. Type sysdm.cpl, and then click OK.

  3. Click the General tab. The operating system is displayed as follows:

    • For a 64-bit version operating system: Windows XP Professional x64 Edition Version < Year> appears under System.

    • For a 32-bit version operating system: Windows XP Professional Version appears under System. Note is a placeholder for a year.




Method 2: View System Information window



  1. Click Start, and then click Run.

  2. Type winmsd.exe, and then click OK.

  3. When System Summary is selected in the navigation pane, locate Processor under Item in the details pane. Note the value.

    • If the value that corresponds to Processor starts with x86, the computer is running a 32-bit version of Windows.

    • If the value that corresponds to Processor starts with ia64 or AMD64, the computer is running a 64-bit version of Windows.
