Check Windows 7 Version
To check the Windows 7 version that you are using on your PC, open up the Start Menu. From there, hover the mouse over Computer, right click, and select Properties from the drop down menu. This should open up the Windows 7 System window, which will be titled "View basic information about your computer."
You should be able to check the Windows 7 version using the very first option in this window. Look for the subheading Windows edition. You should see your version of Windows 7 located directly below this subheading, along with a copyright. Check out the following screen shot if you still cannot find your Windows 7 version.

Windows Experience Index
While you have the Windows 7 System window open, you may also want to take note of some other basic information about your computer.
The subheading directly below Windows edition, System, displays some Windows 7 hardware information about your computer. The first listing, Rating, displays the Windows Experience Index for your PC. This number is an overall rating that Microsoft uses to determine your PC hardware performance. You can click the Windows Experience Index link to get detailed info about your PC.
As you can see from the above screenshot, the overall rating that Windows Experience Index gives your computer is determined by the lowest rated Subscore. For example, you could have the best processor, 16GB of RAM, a 10,000 RPM hard drive, and still have a Windows Experience Index of 3, if you don’t have a premium graphics card. A low Windows Experience Index rating does not necessarily mean that you have a slow computer. However, if all Subscores are 1-2 or lower, you may want to consider upgrading to a faster PC.
The System Screen
The rest of the System screen, located at Start > right-click Computer > Properties, displays which processor you are using, how much RAM your PC has, and whether you are running a 32-bit or 64-bit operating system. This can all be valuable information for updating and upgrading your PC. If you are considering adding more RAM to your PC, you can determine what would be a good upgrade amount, by checking to see how much RAM your PC currently has. If you are considering upgrading to a higher version of Windows 7, you will need to make sure that you are going from 32-bit to 32-bit or 64-bit to 64-bit, if you want to use the Windows Upgrade option. You can go from 32-bit to 64-bit, but it will require a clean install of Windows 7.
The middle portion of the System screen lists the Computer name, domain, and workgroup settings for your PC. You can click the Change settings button to change these listings.
The final portion of the System screen allows you to activate Windows, change product keys, and more.
