+.SYNOPSIS
+    Verifies a PowerToys installation by checking all components, registry entries, files, and custom logic.
+
+.DESCRIPTION
+    This script comprehensively verifies a PowerToys installation by checking:
+    - Registry entries for both per-machine and per-user installations
+    - File and folder structure integrity
+    - Module registration and functionality
+    - WiX installer logic verification
+    - Custom action results
+    - DSC module installation
+    - Command Palette packages
+
+.PARAMETER InstallScope
+    Specifies the installation scope to verify. Valid values are 'PerMachine' or 'PerUser'.
+    Default is 'PerMachine'.
+
+.PARAMETER InstallPath
+    Optional. Specifies a custom installation path to verify. If not provided, the script will
+    detect the installation path from the registry.
+
+.EXAMPLE
+    .\Verify-PowerToysInstallation.ps1 -InstallScope PerMachine
+    
+.EXAMPLE
+    .\Verify-PowerToysInstallation.ps1 -InstallScope PerUser
