⚙️ How I Fully Automated My New Dev Machine Setup. Windows + Terminal (PowerShell + WSL)

Last week I received my new Yoga Pro 9 16IAH10 – Type 83L0 (specs here), and of course… installing everything manually wasn’t an option 😅. So, I automated the entire process — from Windows setup to terminal styling — using PowerShell and a few carefully crafted scripts.

🇪🇸 Spanish Summary / 🇬🇧 English Summary

🇪🇸 La semana pasada recibí mi nuevo Lenovo Yoga Pro 9 y, como era de esperar, no podía instalar todo manualmente 😅. Así que automatizé completamente el proceso con PowerShell: activación de características de Windows, instalación de aplicaciones con Winget, configuración de WSL y personalización de la terminal con Oh My Posh.

🇬🇧 Last week I got my new Lenovo Yoga Pro 9 and, naturally, manual setup wasn’t an option 😅. I automated everything — Windows features, app installs via Winget, WSL setup, and terminal customization with Oh My Posh.

🧭 Prerequisites

Before running anything, open PowerShell as Administrator and allow script execution:

Set-ExecutionPolicy -ScopeProcess -ExecutionPolicyBypass -Force

You’ll also need:

• Windows 11 (Pro recommended)
• PowerShell 7+
• Internet connection
• winget package manager installed
• WSL 2 enabled (optional)

🚀 Step 1️⃣ – Environment Pre-check

Start by verifying your environment with, .\setup.PreCheck.ps1 to validate:

• 👩‍💻 Admin privileges
• 🗂️ Presence of required setup files
• 📦 Winget availability
• ⚙️ Windows features (WSL, Virtualization, Containers, Hyper-V)

If any warning appears, fix it before continuing.
This ensures your setup runs smoothly and without partial installations.

🧰 Step 2️⃣ – Main Setup (Windows Automation)

Run the main script, .\setup.ps1 to:

✅ Enable key Windows features (Containers, WSL, Hyper-V)
✅ Install apps from apps.json using Winget. You can also use your own apps vía winget export in you current environment before move to the new one!
✅ Install and configure Oh My Posh for PowerShell
✅ Copy your Windows Terminal settings and background images
✅ Set up your PowerShell profile with auto-loading prompt themes
✅ Prepare WSL Ubuntu 24.04, including terminal profile integration

🔍 Step 3️⃣ – Post-Install Validation

After installation, run .\setup.PostCheck.ps1 witch confirms:

• Windows features are enabled ✅
• All apps are installed 🧩
• Oh My Posh + Terminal are properly configured 🖥️

🐧 Step 4️⃣ – Configure Oh My Posh inside WSL

Once Windows setup is complete, let’s mirror the same prompt in WSL Ubuntu.

Open Ubuntu (24.04) from Windows Terminal and execute:

bash /mnt/d/Software/setup/setup-omp.sh

This script:

• Installs Oh My Posh in /usr/local/bin
• Copies your theme (my.omp.json) to ~/.poshthemes
• Adds initialization to .bashrc or .zshrc
• Reloads your shell automatically 🎨

Result: identical prompt in both PowerShell and Ubuntu shells.

💡 PowerShell Customization Like a Pro

After the base setup is running, it’s time to make the console shine 😎.

⚙️ Oh My Posh + PSReadLine + Fastfetch

My PowerShell opens with a modern, colorful prompt, smart autocompletion, and a quick system summary.

Install Fastfetch with:

winget install fastfetch

Then configure your $PROFILE like this:

# -----------------------------------------------
# 🎨  OH MY POSH (Prompt Theme)
# -----------------------------------------------
oh-my-posh init pwsh --config "D:\Documents\my.omp.json" | Invoke-Expression

# -----------------------------------------------
# ⚙️  PSREADLINE (IntelliSense + Colors)
# -----------------------------------------------
Import-Module PSReadLine

Set-PSReadLineOption -EditMode Windows
Set-PSReadLineOption -PredictionSource HistoryAndPlugin
Set-PSReadLineOption -PredictionViewStyle ListView
Set-PSReadLineOption -HistorySaveStyle SaveIncrementally

Set-PSReadLineOption -Colors @{
    Command                  = "`e[93m"
    Parameter                = "`e[92m"
    String                   = "`e[33m"
    InlinePrediction          = "`e[90m"
    ListPrediction            = "`e[36m"
    ListPredictionSelected    = "`e[96;7m"
}

# Keybindings
Set-PSReadLineKeyHandler -Chord "Ctrl+Spacebar" -Function MenuComplete
Set-PSReadLineKeyHandler -Chord "F2" -Function SwitchPredictionView
Set-PSReadLineKeyHandler -Chord "Alt+RightArrow" -Function AcceptSuggestion
Set-PSReadLineKeyHandler -Chord "Ctrl+Shift+R" -Function ClearHistory

# -----------------------------------------------
# ⚡ FASTFETCH (System Info on Startup)
# -----------------------------------------------
#To avoid Fastfetch running inside non-interactive terminals (like VS Code tasks):
if ($Host.Name -eq 'ConsoleHost' -and -not ($env:TERM_PROGRAM -eq 'vscode')) {
    fastfetch --logo windows
}
# -----------------------------------------------
# ✅  END OF PROFILE
# -----------------------------------------------

The result:

The Intellisense works like this. If you write, for example «np»:

🐧 Step 5️⃣ – Customize WSL Shell (Bash or Zsh)

The setup-omp.sh script already installs and configures Oh My Posh automatically.
Here we’ll add Fastfetch and optional tweaks to make your Linux terminal match your PowerShell style.

⚡ Install Fastfetch

sudo apt install fastfetch -y

Append to .bashrc or .zshrc so it runs only in interactive sessions:

if [ -t1 ]; then
   fastfetch --logo ubuntu
fi

💡 You can change the logo (ubuntu, debian, arch, etc.) depending on your distro.

🎨 Activate or Adjust Theme (Optional)

The setup-omp.sh script already activates the theme automatically.
If you ever need to re-apply or customize it manually, run:

Bash

eval "$(oh-my-posh init bash --config ~/.poshthemes/my.omp.json)"

Zsh

eval "$(oh-my-posh init zsh --config ~/.poshthemes/my.omp.json)"

💡 You can duplicate and modify the theme (e.g. custom.omp.json) to experiment with colors or segments.

🌀 Optional – Switch to Zsh for better autocompletion

sudo apt install zsh-y
chsh -s $(which zsh)

Now both PowerShell and WSL share the same elegant prompt 💫, with Fastfetch providing a quick system overview every time you open your terminal.

Here is how the WSL (ubuntu) looks like:

🧱 Step 6️⃣ – Post-Installation Tasks

🗄️ DBeaver Projects

Export → Import your projects via File → Export → General → Archive File.

🧩 SQL Server Databases

Backup .bak → Restore on new machine via SSMS.

🐳 Docker Volumes

Backup your docker volumens and then recreate your docker compose (i.e.: docker-compose.yaml) services using:

docker compose -p <YOUR PROJECT NAME> up -d
