The lid and keyboard say it is a Vaio. The plate on the left side of the bottom says "Sony Personal Computer 19.5V" on upper left corner and "Model PCG-61612W" on the upper right. The bottom right has "4-258-229-11". There is a white tag with a serial number on top with 27518883 plus another string of numbers on top, and Service TAG C60803PQ below.
It originally had Windows 7 Home, now it has Windows 10.
Hope this helps!
