How do you know if your Windows XP is 32 bit or 64 bit?

Answer 1

If you have Windows XP, 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 Properties in Control Panel 1. Click Start, and then click Run. 2. Type sysdm.cpl, and then click OK. 3. Click the General tab. The operating system appears as follows: • For a 64-bit version operating system: Microsoft Windows XP Professional x64 Edition Version < Year> appears under System. • For a 32-bit version operating system: Microsoft 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 Processorstarts with x86, the computer is running a 32-bit version of the Windows operating system. • If the value that corresponds to Processor starts with ia64 or AMD64, the computer is running a 64-bit version of the Windows operating system.

Answer 3

If you don't know, you almost certainly have the 32-bit version of Windows XP. The 64-bit version is pretty rare. You can see the version you have by right-clicking My Computer on your desktop or in the Start Menu and selecting properties.

Note that the version of Windows XP you have is not relevant to Windows 8. 32-bit operating systems can run on both 32-bit and 64-bit processors, so having the 32-bit version of Windows XP does not mean that you can't run the 64-bit version of Windows 8.

Answer 4

The fact that you have to ask is an indication that you have the 32-bit version. The 64-bit version had to be specially requested; it wasn't found on the average off-the-shelf computer.
