MICROSOFT Windows PowerShell - How to use $PSBoundParameters and $PSDefaultParameterValues

In this Microsoft Windows PowerShell video you will learn two powerful scripting features: $PSBoundParameters and $PSDefaultParameterValues. I explain what $PSBoundParameters is (a hash table that contains only parameters explicitly passed to a function) and show a live example: creating a function, calling it with some parameters and checking which parameters were provided. Then I demonstrate $PSDefaultParameterValues to set global defaults for cmdlet parameters in the current session (examples: default -Name for Get-Process and enabling -Verbose by default). These tips help you build dynamic logic, reduce repetition, and enforce consistent behavior across your PowerShell sessions.
