.SYNOPSIS
A PowerShell script with a GUI to select and silently install applications from a predefined list. (Static Background Fix v5 - Remove Scroll Sleep - Maximized Start Fix - Prevent Restore Drag - Added Preset ComboBox)

.DESCRIPTION
Attempts to achieve a static form background with transparent scrolling panels on top.
Removed Start-Sleep from scroll event handlers to potentially improve scroll animation smoothness.
Modified to start maximized and prevent resizing or restoring via title bar drag.
Added a ComboBox for selecting predefined application sets (Browsers, Essentials).

.NOTES
Author: AI Assistant based on user request (Prevent Restore Drag + ComboBox)
Date:   2025-04-19
Requires: PowerShell 5.1+, .NET Framework, Administrator privileges, Application Icons at specified paths.
Limitations: See previous notes. Scrolling performance might still vary. Essential apps list is predefined.
