System rating is the measurement calculated by the operating systems in order to let the users know about the quality of hardware devices that are installed in the computers. System rating also allows users to assess which application would run smoothly on the type of hardware configuration a machine has. The feature of system rating was introduced with the release of Microsoft Windows Vista and is now carried forward to almost all operating systems that Microsoft develops.
When Microsoft Windows Vista/Windows 7/Windows 8 is installed on a computer system, the system rating calculated by the operating system automatically is not accurate. Therefore it is recommended that the assessment check should be performed manually after a successful installation of Microsoft Windows operating system.
The process of calculating system rating is an administrative task and therefore elevated privileges are required in order to run or re-run the test. Moreover, while using Windows operating systems on laptop computers, the system rating can be calculated accurately only if they are connected to the direct source of power supply. In case the laptop computers are running on batteries, the operating systems may calculate wrong system ratings, and in many cases the system ratings fall to 1.0.
While calculating system ratings, an operating system calculates the ratings of the below listed hardware devices that are installed on a computer system:
- Memory (RAM)
- Gaming graphics
- Primary hard disk
The operating system calculates the rating of each of the above listed components individually and displays their rating opposite to their respective labels. Apart from displaying the rating of individual hardware components separately, Windows also displays overall system rating in a blue square. The overall system rating is based on the installed hardware component with the minimum rating calculated by the operating system. For example, if the rating of the processor in a computer is 4.0, rating of memory is 4.9, but the rating of primary hard disk is 3.9, the overall system rating would be 3.9 only.
System rating can be seen in the computer properties window that can be initialized by right clicking ‘Computer’ and clicking ‘Properties’ from the context menu.
