First release

System Cleaner 1.1 — what it does.

The first Rainercyb tool is here: a no-nonsense cleaning utility for Windows.

Shows overall system status at a glance via a traffic-light system (green/yellow/red), both overall and per category
Cleans temporary files (user & system) and prefetch files
Empties the Recycle Bin
Removes thumbnail cache, Windows error reports and crash dumps
Clears browser/internet cache and leftover Windows Update files
Cleans up application caches (Discord, Spotify, Adobe, Slack, Microsoft Teams)
Optional: clear DirectX shader cache (incl. NVIDIA/AMD) — off by default since games rebuild it afterwards
Individual categories can be freely selected, including "Select all" / "Deselect all"
Live log shows every cleaning step in real time
Modern dark grey design with rounded corners — fully visible in a normal window, no fullscreen needed
Own program icon, admin-mode detection with one-click restart as administrator
