Starting from Windows XP and now with latest Windows 8, Microsoft offers two types of Windows, one that works on 32 bits and another one that works on 64 bit version.

Step 2: In the new window that opens, in the Overview tab, right click on the line of columns (PID, description, status,…) and from context menu , select Select Columns…
Step 3: From there, just check the box next to the heading “Platform” and confirm by clicking OK.
