Features

Everything w0a can do, page by page, and which parts of it are free. Nothing here is behind a "contact us": the whole tool set is listed.

Free and paid

Half the application is free and stays free — measurement, the 40-switch Optimizations page, the repair cards, backups and the maintenance tools. A plan opens the ten pages that change the machine most deeply. The table below is the whole division; there is no third tier.

What is free, what a plan opens

Where a licence key goes, and what each activation error means

Monitoring and sensors

Live clock and temperature for the processor and the graphics card, memory in use, and the mouse polling rate measured from real movement rather than read off a spec sheet. Usage and fan speed are read for the graphics card only, on its own page, which a plan opens; there is no CPU fan reading. Polling stops while a game is in the foreground: a sensor read takes the graphics kernel lock, and doing it every two seconds during a match is a stutter you can feel.

What the stutter scan reads, and why it waits for the game to close before touching sensors

Optimizations and checks: 160+, every change reversible

Two pages carry the catalogue. Optimizations is free and holds 40 switches — core parking, Game DVR, fullscreen optimizations, mouse acceleration, prefetch, visual effects and the rest. Regedit Tweaks is on a plan and holds the deeper set: background capture, consumer feature suggestions, Delivery Optimization upload sharing, input queue sizes, Explorer startup delay, window animations. Every switch that writes a new value records what was there before; the two that only put a Windows default back are undone from the Fix page instead.

What each group of tweaks actually does: input · display · audio · memory · background · startup

Display and graphics: the driver timeout put back, and window animations

Audio: what raising the audio engine's scheduling priority does

Memory and disk: merging service processes, and what that costs

Silent load: the trace sessions and scans Windows starts by itself

Startup and background: boot delay, update sharing, and restarts mid-match

Game optimization

A CS2 profile with 16 per-game switches, the Steam launch options editor, and a video-config page that reads and writes the game's own settings file — after backing it up. These are the only game files w0a ever writes; it injects no code into game processes and reads none of their memory.

If CS2 will not start or its video settings look wrong after a change

Network and ping

Delayed ACKs off, network throttling lifted, adapter power saving disabled and Energy Efficient Ethernet off. Separately, a DNS resolver test that measures the real resolvers from this machine and a ping test against game servers. How much any of it helps depends on your connection and your route.

Box by box on the Internet page: what each one writes, and which of them can change a match

If pages stop loading or names stop resolving, putting DNS and the network stack back

Process manager and the background engines

Eight engines, all off on a fresh install and each turned on separately. Auto Priority raises the game and its helper processes the moment it comes to the foreground. Balance Mode holds background work down while a game runs and hands it back when the game closes. Reserved Cores moves everything that is not the game onto the machine's background half. Game Boost keeps the game's memory resident and raises its GPU scheduling class. Indexer Hold drops the Windows Search indexer to the lowest priority until the game closes. Sleep Guard keeps the machine awake and the display on while you play. Wi-Fi quiet stops the wireless adapter leaving its channel to scan during a match. w0amax Power Plan switches Windows onto a plan with no core parking and no frequency drop. Separately, affinity rules pin a named program to the processors you choose, permanently.

Power plans

A laptop plan and a maximum-performance plan (w0amax), both created by w0a rather than edited in place, plus a full custom-plan editor: processor floor and ceiling, core parking, idle and display timeouts, USB selective suspend, PCI Express link state.

Going back to Balanced, and what happens to the plans w0a created

Graphics card

Live clock, voltage, memory clock, temperature, fan and load, with power limit and clock offset sliders, a fan curve editor, and an auto tuner that measures throughput after each step and reverts itself if the driver resets. The default only lowers the power limit; overclocking is opt-in. There is also a CS2 driver profile and a P-state hint; those two are written into the driver's own profile database rather than to the card, so undoing everything else leaves them in place — each has its own Revert button, and the NVIDIA card on the Fix page removes them too.

Memory

Timings read live from the memory controller's own registers, frequency and per-slot information from the modules, a bandwidth measurement, and a memory cleaner that trims working sets on a schedule you set — with running games protected from it. The detailed timing tables need the signed PawnIO driver and cover AMD Zen 1 to Zen 5 for now; on Intel the memory speed and the XMP state are shown instead.

Latency and measurement

The Latency Test measures the input report tail from real mouse movement and the DPC/ISR time of each driver on the machine, so a stutter can be traced to the driver causing it. Stutter Detective scans for the usual causes. Benchmark reads frame times from Windows' own event stream — no overlay, no injection — and reports average FPS, 1% low and stutters per minute as before/after pairs. The 1% low is the number that matters: an average can rise while the game feels worse.

Maintenance

Startup manager, an uninstaller that also clears what the installer left behind, a graphics-driver version check, application updates through winget and a BIOS age note, and log cleaning that says exactly which folders it will empty before it touches them. Deletions are permanent and the app says so before it deletes anything.

Undo: backups and the Fix page

Every registry and power-plan change is written to a log with the value that was there before, grouped into checkpoints you can revert one at a time or all at once. The Fix page is the other half: a repair card for each area that can be changed, each writing the Windows default back unconditionally — so a machine can be repaired even if it was never touched by w0a, or if the log is gone.

How undo works, in detail

If Windows can no longer create restore points

What it deliberately does not do

No kernel-level values are written. No MPO or TDR key is ever written — on a real machine those froze CS2; they are only deleted, and only to put the Windows default back. No code is injected into games and no game memory is read. There is no driver of its own; the signed PawnIO driver used for CPU temperature and RAM timings installs only if you approve it, and only reads.
