Can't tell anything from that limited screenshot. It's like giving you a picture of a football field, showing only the grass, and asking what team is this?
Please post your full system specs including the EXACT model numbers of all hardware, or at least as much as possible.
CPU, motherboard, power supply, memory, storage drives, operating system version and bit depth, graphics card, etc.
Please also post the full screenshot showing what is running and which applications are using each of those percentages of physical memory.
Including a list of all software and applications that you know for sure are running would be helpful too.
