Determine what Windows operating system you are running

Here is an easy way to check what version of the Windows operating system you are running on your computer.

There are two ways to do this:

1. Open the Run window by going to Start > Run

Run Dialog

2. Open the Command Prompt (normally located under Start > All Programs > Accessories > Command Prompt).

Command Prompt

Type “winver” into either dialog and hit Enter.

You should then see an About Windows dialog box like this:

About Windows

The top line will give you the operating system name and version (Professional, Ultimate, etc.). You can also get information such as the Version number, Build number and which Service Pack has been installed. There is also licencing information relating to the operating system.
