+
+<#
+.SYNOPSIS
+    Installs black screen overlay to hide Windows logon animations.
+
+.DESCRIPTION
+    Creates and installs a fullscreen black overlay that covers the logon UI
+    animations, combined with registry tweaks for maximum suppression.
+    The overlay automatically dismisses when the desktop shell loads.
+
+.NOTES
+    - Requires Administrator privileges
+    - Creates overlay executable and scheduled task
+    - Combines with registry animation suppression
+    - Completely safe - no system file modifications

+Write-Host "`n📋 WHAT WAS INSTALLED:" -ForegroundColor Cyan
+Write-Host "  ✓ C# source code: $csPath"
+Write-Host "  ✓ Overlay executable: $exePath"
+Write-Host "  ✓ Scheduled task: Runs at system startup (highest priority)"
+Write-Host "  ✓ Registry tweaks: Core animation suppression applied"
+Write-Host "  ✓ Security: SYSTEM-level execution with highest priority"
+
+Write-Host "`n💡 HOW IT WORKS:" -ForegroundColor Green
+Write-Host "  1. At boot, black overlay launches before LogonUI"
+Write-Host "  2. Covers ALL screens with solid black window (multi-monitor aware)"
+Write-Host "  3. Uses Rectangle.Union for proper multi-monitor coverage"
+Write-Host "  4. Stays on top of all animations and UI elements"
+Write-Host "  5. Monitors for explorer.exe (desktop shell)"
+Write-Host "  6. Waits 1000ms after shell detected (slow system support)"
+Write-Host "  7. Dismisses itself gracefully"
+Write-Host "  8. Result: Completely black transition to desktop"
+
+Write-Host "`n🎯 WHAT YOU'LL SEE:" -ForegroundColor Green
+Write-Host "  • Windows logo during boot (normal)"
+Write-Host "  • Solid black screen (instead of animations)"
+Write-Host "  • Your desktop appears smoothly"
+Write-Host "  • NO profile picture, username, spinning wheel, or status text"
+
+Write-Host "`n🖥️  MULTI-MONITOR SUPPORT:" -ForegroundColor Green
+Write-Host "  • Covers horizontal screen layouts"
+Write-Host "  • Covers vertical screen layouts"
+Write-Host "  • Covers mixed/irregular layouts"
+Write-Host "  • Uses Rectangle.Union for proper bounds calculation"
+
+Write-Warning "`n⚠️  IMPORTANT NOTES:"
+Write-Host "  • Overlay has 10-second timeout (safety mechanism)"
+Write-Host "  • 1000ms delay after explorer.exe for slow systems"
+Write-Host "  • Auto-restart on failure (3 attempts)"
+Write-Host "  • Works with auto-login and password-protected accounts"
+Write-Host "  • Battery-friendly (runs on laptop battery)"
+Write-Host "  • Restart required to see it in action"
+
+Write-Success "`n✅ ADVANTAGES:"
+Write-Host "  • Compiled with csc.exe for better compatibility"
+Write-Host "  • Fallback to Add-Type if csc.exe unavailable"
+Write-Host "  • No system file modifications"
+Write-Host "  • No security compromises"
+Write-Host "  • Update-proof (survives all Windows Updates)"
+Write-Host "  • Fully reversible (use uninstall script)"
+Write-Host "  • Zero performance impact"
