v2.1.0 — 49 tweaks + standalone PowerShell engine (no exe needed)

The .bat now does everything — the exe is optional. One file, both modes, full CLI.

New

• 19 new tweaks (49 total): VRR, Optimizations for windowed games, Auto-HDR off, Game Bar off, MSI mode, GPU interrupt affinity, TCP BBR2, NIC / USB / PCIe power management off, bigger DNS cache, fast startup, taskbar & transparency tweaks, cursor trails off, balanced visual FX, recycle-bin confirm
• Single OptimizeKit.bat — menu (full kit with UAC / user kit / status / restore / dashboard) plus CLI passthrough: OptimizeKit.bat -Status, -Apply id1,id2, -Profile gaming|privacy|debloat|full, -Silent, -RestoreAll
• PowerShell engine v2.1 — full parity with the C++ catalog, -Status reads the machine (never a memory), DNS resolver benchmark, diagnostics (clock, DPC/ISR, jitter/loss, disk latency), one-key Restore All
• OptimizeKit-NIC.ps1 — hardware-aware NIC tuning: only touches advanced properties your adapter actually exposes, JSON backup + restore per adapter
• Settings → Language: English (base) / Français, persisted
• New Diagnostics view with honest measured numbers (CPU clock, DPC/ISR %, ping/jitter/loss, disk latency, running game detection)

Fixed

• v2.1 tweak ids had no apply branches (they returned "unknown tweak id" when clicked) — all wired now
• VRR wrote to the wrong registry path; PCIe ASPM restored to the wrong value
• Mouse acceleration values were written as REG_DWORD (Windows expects REG_SZ)
• Tweaks page: switches, badges and counters fully working; decorative emoji stripped

Safety

Every tweak still one-click reversible, every apply snapshot-backed to %LOCALAPPDATA%\OptimizeKit\backups, -RestoreAll returns the whole catalog to Windows defaults.
