The easiest way to take a screenshot is to use a Snipping Tool program provided by the Windows operating system. The tutorial on how to do it has been presented in the video below:

Additionally, you can press the “Print Screen” or “PrtScn” button on your keyboard. Then open the editing software, such as “Paint” or “Adobe Photoshop”, and press the “Ctrl” and “V” buttons on your keyboard at the same time. Save the file to .jpg or .png format. 

Alternatively, if you are using Windows 8, 8.1, or 10, you can do it much faster:

Press "Windows Key" and "Print Screen" or "PrtScn". The screenshot will be automatically saved in the "Screenshots" folder (C:\Users\[user]\Pictures\Screenshots).

You can also provide us with screenshots by using dedicated tools or programs for example: gyazo.com

Note: Screenshots have to be always unedited and full, which means the taskbar with the time and date are necessary as well.
