Safety, compatibility, and deployment notes

• Always test on a disposable VM or secondary machine first; don’t deploy to critical work systems without validation.
• Create a full system backup or image before applying changes so you can revert.
• Keep Windows and drivers updated separately; some tweaks may be undone by Windows Feature Updates and require reapplication.
• Anti-cheat systems (EasyAntiCheat, BattlEye) and some DRM may refuse or malfunction on heavily modified systems; verify on a per-game basis.
• Use community documentation and change logs to understand which tweaks are applied and how to revert individual changes.

• You have a Steam Deck or a low-end gaming laptop.
• You are building a dedicated emulation box.
• You are a competitive gamer chasing every millisecond of latency.
