The optimizer that proves its work.

A free Windows 11 tuning app — debloat, privacy, verified tweaks and a hardware scan. What makes it different is not the tweak list. It is that every tweak tells you its risk, how strong the evidence behind it actually is, and exactly what you lose by applying it. Where a popular "optimization" is placebo, it is labelled placebo or not shipped at all.

The catalogue is the product

Thirty-two tweaks, all of them declarative data in an open file you can read, audit and edit without rebuilding anything. These are real entries, with their real labels — filter by how good the evidence actually is.

Evidence

    Nothing here is graded generously. Two tweaks are labelled unproven and ship anyway, clearly marked, rather than being quietly dressed up as improvements. Three are rated caution because they are a real trade, not a free win.

    What it refuses to do

    A failed backup aborts the whole apply

    The app always writes a backup first, and if that backup fails, nothing is changed at all. Half-applied is the state that ruins an afternoon, so it is designed to be unreachable.

    True state capture

    Your machine's actual values are journaled before every change. Revert restores what was really there — never an assumed default.

    Undo that outlives the app

    Each backup folder holds the prior values as JSON, a double-clickable .reg undo that works even if TuneMyPC is uninstalled, and plain-English instructions. Backups survive uninstall on purpose.

    Nothing coercive

    No fake scan results, no alarmist counters, no bundleware, no pay-to-fix. The design brief cites Microsoft's PUA criteria and FTC v. Restoro by name.

    Reversible at every level

    Per tweak, per session, or everything at once — including at uninstall, where it offers to undo every change before it goes. A restore point per session is the second net, and scheduled tasks are disabled rather than deleted so Windows can put them back.

    It names the myths

    The scan flags "optimizations" that other tools left on your machine and explains why they are placebo or harmful — without silently undoing them behind your back.

    Three it calls out by name:

    • The 20% reserved-bandwidth myth — QoS never reserved your bandwidth in the first place.
    • Disabled prefetching — usually a straight loss, especially on the machines it was supposed to help.
    • Cargo-cult scheduler values, copied between forum posts for a decade.

    Naming them is the point. An optimizer that quietly reverses another tool's damage teaches you nothing, and asks for exactly the trust the last one abused.
