Five tools. One licence system.

Click any product to see what is inside it and what its key looks like. Each one has its own key prefix — a Duster key never unlocks Movement, and a Movement key never unlocks the cleaner. What you own shows up in the app.

Why RFBZ

Built to be trusted with your machine

Keyed, not cracked

Every tool asks this server whether your key is live before it runs, so a revoked key stops working and an update reaches you the next time you launch.

Nothing left behind

Each install first removes the previous version — processes, tasks, auto-run entries and stale folders — and the uninstaller takes the rest on request.

Updates itself

The app checks this server each time it opens and installs a newer build by itself, after verifying it to the byte. There is no version to go and hunt for, and nothing to reinstall.

You see the changes

Duster scans and lists what it found before it touches anything. Opti backs up what it changes, so a tweak you dislike is a restore away.

Made to be fast

The engine is a single self-contained binary with no runtime to install, so it starts instantly on a clean Windows install.

Support that answers

Questions go straight to the person who built it. If a key stops working, message with the key and what changed on the PC.

FAQ

Straight answers

What do I get when I buy a key?
A licence key for one product, and that product inside the RFBZ app. Create an account, paste the key once, and what it unlocks appears on your shelf — rechecked against this server every time the app opens.
Is one key enough for my whole PC?
Yes — a key is for a machine, not a number of launches. For the cleaner that goes further: it locks to the hardware it first ran on, which is why a Duster run is armed per use from the app rather than reused.
Why is there nothing to download on this page?
Because a public installer is one anybody can take. The tools live in the app, which is tied to your account and asks this server whether your key is live before it hands anything over — so a copy passed around is worth nothing to the person holding it.
How do updates work?
By themselves. Each time the app opens it asks this server for the current build, and if it is newer than the one you have it downloads it, checks it against the hash the server published, and installs it — restarting once on its own. You will see a line in the app while that happens and nothing else.
How do I remove everything?
Uninstall it the way you would any other Windows program, or use the uninstaller that ships with each tool: it removes the folders, shortcuts, scheduled tasks, run-key entry, firewall rules, Defender exclusions and the saved licence. Removing the key from your account locks the product out; it is the uninstaller that scrubs the machine.
My key stopped working.
Keys can be revoked, and the cleaner's keys are bound to one machine. Message the seller with the key and what changed on your PC — a hardware change is the usual cause.
Get a key

One key, one product, straight to your account

Every product above is unlocked by its own key, and each key is issued per machine. Ask for the one you want and it lands on your account, ready the next time the RFBZ app opens.

1Ask for your key

Say which product you want — Duster, Opti, Movement or Macro. One key unlocks one product, and a key for one never opens another.

2Install the RFBZ app

The app for Windows. One installer, no runtime and no dependencies to add first.

3Add it to your account

Sign in, paste the key once, and the product appears. The server is asked whether the key is live — a revoked key re-locks itself the next time the app opens.
