Windows Setup for Power Users

Most practitioners don't need this page

If you just want to run workflows, open claude.ai in any browser — nothing to install. This page is for builders/power users who want Claude Code (and optionally other CLI assistants) running locally on Windows. See Power Users: Claude Code & Cowork for the full picture.

What You'll Install

Tool Purpose
WinGet Microsoft's package manager for quick terminal installs
PowerShell 7 Modern terminal with better features
Node.js / NPM Runtime for Claude Code (and other CLI assistants)
UV / UVX Fast Python package installer (like pip, but faster)
Claude Code Anthropic's CLI coding assistant

Step 1: Install Prerequisites

Open PowerShell as Administrator

  1. Click Start Menu
  2. Search for PowerShell
  3. Right-click → Run as Administrator

Enable Script Execution

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Install Node.js and UV

winget install OpenJS.NodeJS astral-sh.uv

WinGet not recognized?

If WinGet isn't available, install it first: 

Install-Module -Name Microsoft.WinGet.Client

Upgrade to PowerShell 7

winget install --id Microsoft.PowerShell --source winget

Restart Required

Close and reopen PowerShell after installation. Verify you're running PowerShell 7 by checking the window title.

Step 2: Install AI Coding Assistants

irm https://claude.ai/install.ps1 | iex

You can log in to each with your existing Google, Anthropic, or OpenAI accounts.
