The correct cmdlet utilized to shut down local or remote computers in PowerShell is Stop-Computer. This cmdlet is specifically designed for this purpose and allows administrators to perform shutdown operations on both local and remote systems effectively.

When using Stop-Computer, you can specify parameters such as `-ComputerName` to indicate the target machine, and `-Force` to execute the shutdown without confirmation. For instance, `Stop-Computer -ComputerName "RemotePC" -Force` would forcibly shut down the named remote computer.

The accurate syntax of this cmdlet is critical in PowerShell since it is case-sensitive when considering parameters and structured commands. The proper hyphen before "Computer" is essential, as it distinguishes the cmdlet from other potential similarly named functions or variables.

In contrast, other options provided either lack the correct syntax or do not exist as valid PowerShell cmdlets. For example, "Shutdown-Computer" and "ShutdownComputer" do not represent any known cmdlets in PowerShell, therefore they would not work for performing the desired shutdown operation. "StopComputer" also misses the necessary hyphen and does not correspond to a valid cmdlet, confirming that only Stop-Computer is the appropriate and functional choice for shutting down computers
