1. A comprehensive comment-based help section at the beginning, which provides information about the script’s purpose, parameters, examples, and more.
2. #Requires statements to specify prerequisites like PowerShell version, required modules, or administrator rights.
3. [CmdletBinding()] attribute to make the script behave like a cmdlet.
4. Parameter block with examples of mandatory and optional parameters, including parameter attributes.
5. Begin, Process, and End blocks to structure the script’s execution.
6. Error handling with try-catch blocks.
7. Logging functionality to keep track of the script’s execution.
