How to determine the version of Windows that is installed on a computer

This guide will explain how you can determine what version of Windows is installed on your computer and whether its a 32-bit or 64-bit installation.

If your Windows Start button looks like this , then please follow these steps:

• Click on the Windows Start button.
  
  
  
• You should now see a screen similar to the one below:
  
  
  
  Please right-click on the Computer icon as shown in the image above and select Properties.
  
  
  
• The System Properties screen should now open that displays the Windows version and whether or not it the operating system is 32-bit or 64-bit.
  
  
  
  The information on the version of Windows that is installed on your computer can be found under the Windows Edition section, which I have indicated with the blue arrow. Whether or not the installation is 32-bit or 64-bit can be found on the System Type row as designated by the red arrow in the picture above.

If your Windows Start button looks like this , then please follow these steps:

• Click on the Windows Start button.
  
  
  
• You should now see a screen similar to the one below:
  
  
  
  Please right-click on the My Computer icon as shown in the image above and select Properties.
  
  
  
• The System Properties screen should now open that displays the Windows version and whether or not it the operating system is 32-bit or 64-bit. Please note that this screen will only display if the operating system is 64-bit. If it does not specifically state 64-bit, then it is a 32-bit installation of Windows.
  
  
  
  The information on the version of Windows that is installed on your computer can be found under the System section, which I have indicated with the blue box.
