One flat catalog. Every card shows the exact change.

How the catalog works.

• Search the whole catalog — one searchable list, no category hunting.
• Every card states the verbatim change — plus a plain-language line in English.
• A System Restore point is made first — created before the first change applies.
• Everything is reversible from History — per tweak, per session, or all at once.

Privacy — cut tracking at the source.

The category CRY started with. Turns Windows' data collection down at the registry key and the service, not behind a vague switch.

• Diagnostic Data (Telemetry) — reduced to minimum.
• Connected User Experiences and Telemetry — disable DiagTrack.
• WAP Push Message Routing — disable dmwappushservice.
• Advertising ID — disabled.
• Activity History / timeline, Feedback notifications & Consumer Features — disabled.

Performance — no placebo.

No fake RAM cleaners, no "boost" buttons. A handful of changes that affect foreground responsiveness, each shown verbatim.

• Foreground CPU quantum — bias the scheduler toward the app you're using. Win32PrioritySeparation = 0x26
• High Performance power plan — stop the CPU throttling down under light load. powercfg /setactive SCHEME_MIN

Gaming — frames, not folklore.

GPU scheduling, Game Mode, Game DVR and the multimedia scheduler (MMCSS) — changes that affect latency and frame pacing, with the verbatim key on every card.

• Hardware-Accelerated GPU Scheduling (HAGS) — HwSchMode 0 → 2
• Game Mode — enabled; Game DVR / Background Recording disabled.
• Games Task Profile (MMCSS) — raise CPU priority.
• SystemResponsiveness — lower reserved CPU and switch to High Performance during play.
• Foreground App CPU Quantum — optimized; Fullscreen Optimizations (FSO) disabled globally.

Network — lower latency.

Trim background chatter and tune the TCP stack — autotuning, Nagle's algorithm, the network throttling index, and DNS — via registry and netsh. CRY records the previous state so undo is precise.

• TCP autotuning — netsh int tcp set global autotuninglevel=normal
• Nagle's algorithm — an advanced change worth understanding first. TcpAckFrequency = 1
• Network throttling index & DNS — tuned for responsiveness.

Bloatware — removed, reinstallable.

Uninstall bundled UWP apps via winget / appx, and reinstall any of them later. Nothing is deleted irreversibly.

• Bundled UWP apps — uninstall via winget / appx. winget uninstall <PackageId>
• Reversible — reinstall any removed app later.

Startup — stop boot-time clutter.

Disable services and tasks that don't need to boot with Windows. Some need a sign-out or restart to take effect; the card says so up front.

• Startup services & scheduled tasks — disabled where safe.
• Restart-required changes — labelled clearly on the card.

Recommended, Optional, Advanced.

Every tweak carries a badge for how safe a default it is. They're guidance, not gates: you decide, the review gate confirms, and you can undo.

• Recommended — broadly safe, well-understood changes.
• Optional — beneficial for some setups, harmless to skip.
• Advanced — know what it does before you apply it.

Presets — stage once, share a code.

Build a selection, then save it as a named preset or export it as a portable cryset: code. Paste one in to import someone else's setup — it still goes through the same review gate before anything runs.

App Installer — common apps, a couple of clicks.

Pick what you want and CRY installs it. It detects what's already present and marks those Installed, so you don't reinstall over a working app.

• Browsers — Google Chrome, Mozilla Firefox, Brave.
• Developer — VS Code, Git, Python 3, Node.js LTS, Windows Terminal, PowerToys.
• Media — VLC, Spotify.

Dashboard & History — watch the machine, revert anything.

The Dashboard reads live performance counters. History keeps a local, append-only log of every applied change, so undo is never a guess.

• Dashboard — live CPU and Memory readouts from real PDH counters, drawn as sparklines, with system info and a Safety / System Restore card.
• History — every applied change logged locally under %LOCALAPPDATA%\CryOptimizer. Revert one tweak, a session, or everything.
