The Windows Experience Index score is not displayed in Windows 8.1 and onwards because the graphical user interface for WinSAT was removed in these versions of Windows, although the command line winsat tool still exists and operates correctly along with a final score when launching the command "shell:games".

The first machine to use out-of-order execution was the CDC 6600 (1964), designed by James E. Thornton, which uses a scoreboard to avoid conflicts. It permits an instruction to execute if its source operand (read) registers aren't to be written to by any unexecuted earlier instruction (true dependency) and the destination (write) register not be a register used by any unexecuted earlier ...
Scoreboarding is a centralized method, first used in the CDC 6600 computer, for dynamically scheduling instructions so that they can execute out of order when there are no conflicts and the hardware is available. [1] In a scoreboard, the data dependencies of every instruction are logged, tracked and strictly observed at all times. Instructions ...
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.
In a computer instruction set architecture (ISA), an execute instruction is a machine language instruction which treats data as a machine instruction and executes it.. It can be considered a fourth mode of instruction sequencing after ordinary sequential execution, branching, and interrupting. [1]

The term execute is also ambiguous. It may refer to running the code identified by the command object's execute method. However, in Microsoft's Windows Presentation Foundation a command is considered to have been executed when the command's execute method has been invoked, but that does not necessarily mean that the application code has run ...
