Windows PowerShell
Windows PowerShell is the terminal built into Windows: a window where you control your computer by typing commands. The entire installation guide happens inside it — winget, git clone, npm install, claude mcp add run one after another. Open it from the Start menu by typing “PowerShell.” One small catch: by default, Windows blocks certain scripts from running; the Set-ExecutionPolicy RemoteSigned command allows local scripts (and downloaded scripts if they’re signed) — sometimes needed to launch tools installed via npm. Once that door is open, the guide’s commands run one after another without a hitch.
