How it worksFive steps, full control

The process

Five steps. Full control.

Both products follow the same disciplined flow. Every step is guided. Every change is reversible.

01ScanHardware, services, startup items, telemetry state, work environment signals — read before anything is touched.

02ClassifyGaming desktop, work PC, laptop, low-spec, VM — classified with confidence scoring, not guesses.

03PlanProfile-aware action list. Work PCs keep printing and RDP. Gaming desktops get latency tuning. Nothing blind.

04ExecuteLive application with per-action rollback snapshots. Every change visible in real time as it runs.

05ValidateRegistry read-back, benchmark comparison, full report. You know exactly what changed and why.
