+.SYNOPSIS
+    Enables all Windows features required for WSL 2 on Windows 11 and installs the latest Ubuntu distribution.
+
+.DESCRIPTION
+    This script must be run as Administrator. It will:
+      1. Enable the "Microsoft-Windows-Subsystem-Linux" and "VirtualMachinePlatform" optional features.
+      2. Set WSL 2 as the default WSL version.
+      3. Install/update the WSL kernel components.
+      4. Install the latest Ubuntu distribution from the Microsoft Store catalog (via `wsl --install -d Ubuntu`).
+
+    A restart may be required after enabling the Windows features for the first time. If a restart is
+    needed, the script will detect it, prompt you, and re-run automatically after reboot (via a scheduled
+    task) unless you decline.
+
+.NOTES
+    Run this script from an elevated PowerShell prompt:
+        powershell -ExecutionPolicy Bypass -File .\Install-WSL2Ubuntu.ps1
+#>
+
+[CmdletBinding()]
+param(
+    [string]$Distribution = "Ubuntu"
