"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

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

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.
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

Click Start, and then click Run.
Type sysdm.cpl, and then click OK.
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

Click Start, and then click Run.
Type winmsd.exe, and then click OK.
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.

As for hardware question, what hardware are you running?"

"Open a command prompt and type set proc.

If the output includes PROCESSOR_ARCHITECTURE=AMD64, you're using 64-bit Windows.
If the output includes PROCESSOR_ARCHITECTURE=x86, you're using 32-bit Windows. However, if the output also includes PROCESSOR_ARCHITEW6432=AMD64, this means that you're running a 32-bit command interpreter on 64-bit Windows."

"If you're stuck in a computer lab that has everything locked down for ""security"" reasons (like those at my university), you can still run CMD and type in SystemInfo.

Once that's completed running, scroll to the top of the list and locate ""System Type:"". I can't remember what it says on a 64 bit OS, but a 32 bit says ""x86-based PC"". That being said, a 64 bit OS will probably say ""x64-based PC""."
