!K3rnalyze

!K3rnalyze is a research-driven tweaking toolkit. It does not ship pre-applied profiles, you choose exactly what to change across Windows, CPU/GPU, and BIOS/MSR.

Every toggle is grounded in real debugging and measurement. The goal is transparent, granular control: you see what each tweak targets and apply only what you need for your workflow or game.

  • Broad coverage: Windows internals, scheduling/MMCSS, timers, power policy, memory & Cache Manager, networking, and driver-level knobs.
  • Granular controls: clearly scoped switches with concise descriptions and notes.
  • Selectivity by design: nothing is applied automatically; you opt-in tweak by tweak.
  • Expert options separated: MSR/BIOS-adjacent items are grouped and labeled for experienced users.
  • Standalone or with KernelOS: integrates nicely with KernelOS, but works on stock Windows too.

Research in action

Behind every toggle in !K3rnalyze there’s real debugging and analysis. We dive into Windows internals, schedulers, and drivers; so you don’t have to.
