Set Up a Windows PC for AI Development in One Command

A single PowerShell command that installs everything you need for AI-assisted development — Node.js, Python, Git, VS Code, Google Antigravity, and OpenCode — silently, in about 10–15 minutes.

How to Run It

Step 1 — Press Start, type powershell, right-click → Run as administrator

Step 2 — Paste this entire command and press Enter:

(or Antigravity)" -ForegroundColor Green; Write-Host "First launch of Antigravity/OpenCode asks you to sign in with Google." -ForegroundColor Yellow

Step 3 — Wait 10–15 minutes (progress shows as >>> markers; most time is Google Antigravity's download)

Step 4 — When you see DONE, close & reopen PowerShell

Step 5 — Verify:

PowerShell

node --version

npm --version

python --version

git --version

code --version

opencode --version

What the Command Does

#StepDetails1Check wingetInstalls Windows Package Manager if missing2Install core toolsNode, Python, Git, VS Code, Antigravity, Terminal, 7-Zip — all silent3Refresh PATHTools work without reboot4Install OpenCodenpm install -g opencode-ai5Create workspaceC:\Users\<you>\ai-workshop6VerifyPrints versions, marks [OK] / [FAIL]7LogEverything saved to workshop_setup.log

Notes

1. Admin required — must run as Administrator or installs fail
2. Re-run is safe — already-installed tools are skipped
3. First launch — Antigravity & OpenCode ask for Google sign-in once (normal)

fix the Execution Policies
