PowerShell is typically preinstalled on modern Windows desktop and server platforms. If it is not present, you can download and install it by searching for Windows Management Framework 5. Both PowerShell and the PowerShell ISE (Integrated Scripting Environment) are free.
The author recommends using PowerShell ISE when learning because it provides:
- An integrated environment — makes it easier to discover and experiment with PowerShell CmdLets
- Script development tools — write, test, and debug scripts in one place
- Context-sensitive help — get help on commands without leaving the environment
- Automatic command completion — speeds up both development and learning
To launch PowerShell ISE on Windows, open the Start Menu, search for "PowerShell ISE," and click the app.
This hands-on, experimental approach pairs well with learning techniques like Active Recall and Spaced Repetition: instead of just reading about PowerShell, you try commands immediately, make mistakes, and learn by doing.
