What is PowerShell?

PowerShell is Microsoft’s object-oriented shell for Windows administration and defense scripting.

Query event logs, manage systems, and automate Windows labs.

Official website: PowerShell · Documentation

When do you use it?

  • You need Windows automation shell, crucial for admins and defenders.
  • You are following a CYNARKS lab or authorized engagement that calls for PowerShell.
  • You already tried simpler checks and need this tool’s deeper capability.

Who uses it?

  • Security practitioners
  • Students in authorized labs
  • Engineers validating their own systems

How do you use it? (typical flow)

  1. Install PowerShell using the steps below (prefer Kali package or official installer).
  2. Confirm you have authorization for the target (lab VM, own system, or written scope).
  3. Run --help / man (or the Help section) to see current flags for your version.
  4. Start with a safe example from Basic commands against localhost or an authorized lab target.
  5. Record what you ran, what you observed, and any follow-up (filter, report, remediation).
