OD858 — Personalize Your Windows PC with AI: Build a Copilot Skill

Tell an AI assistant _"make everything pink!"_ and watch it transform your RGB lighting, desktop themes, and more. This session shows how to build a GitHub Copilot Skill that personalizes Windows using natural language — from Dynamic Lighting effects to full desktop theming.

🏠 Getting Started (Own Environment)

Follow these steps after Build to set up the skill on your own machine.

Prerequisites

| Requirement | Version | Install | |---|---|---| | Windows 11 | 22H2+ | — | | Git | Any | winget install Git.Git | | .NET SDK | 9.0+ | winget install Microsoft.DotNet.SDK.9 | | Python | 3.10+ | winget install Python.Python.3.12 | | WinAppCLI | 0.2+ | winget install Microsoft.WinAppCli | | Developer Mode | — | Settings → System → For developers → ON | | Dynamic Lighting device | — | Any compatible RGB device |

Quick Install

# Install all prerequisites at once
winget install Git.Git Microsoft.DotNet.SDK.9 Python.Python.3.12 Microsoft.WinAppCli

# Clone the maintained repo as a Copilot skill
git clone https://github.com/samanthamsong/windows-personalization-skill.git "$HOME\.copilot\skills\windows-personalization"
cd "$HOME\.copilot\skills\windows-personalization"

# Run setup (first time: run as admin)
Start-Process powershell -Verb RunAs -ArgumentList "-File $PWD\setup.ps1"

> Windows Settings (do both before running setup): > 1. Developer Mode: Settings → System → For developers → Developer Mode (ON) > 2. Dynamic Lighting: Settings → Personalization → Dynamic Lighting → "Use Dynamic Lighting on my devices" (ON)

Try It

# Set your keyboard to a color
python modules/dynamic-lighting/lighting.py set-color "#FF6600"

# Run a per-lamp effect
python modules/dynamic-lighting/lighting.py run-effect koi-fish

# Or just tell Copilot what you want:
# "Make my keyboard breathe with purple"
# "Ocean waves on my keyboard"

🎯 Learning Outcomes

After this session, you will be able to:

• ✅ Build a Copilot Skill — create a SKILL.md and module structure that AI agents can discover and invoke automatically
• ✅ Control Windows Dynamic Lighting — use the LampArray API with .NET + Python to create per-lamp RGB keyboard effects
• ✅ Create natural language interfaces — connect human prompts ("make it pink!") to system-level Windows personalization APIs
• ✅ Theme your entire desktop with AI — orchestrate wallpaper, accent colors, and RGB lighting from a single prompt

💬 Keep Learning with Copilot (Suggested Prompts)

Paste these into GitHub Copilot Chat (with the [Microsoft Learn MCP Server](#-microsoft-learn-mcp-server) connected) to explore further:

1. "How do I create a custom Copilot Skill that controls hardware APIs on Windows? Show me the SKILL.md format and how agents discover skills."

2. "Walk me through the Windows Dynamic Lighting API — how does a .NET app register for LampArray access, and how can Python scripts control individual lamp colors?"

3. "I want to build a theme engine that changes wallpaper, accent colors, and keyboard lighting from a single natural language prompt. What Windows APIs and patterns should I use?"
