New RFBZ Duster is live → RFBZ emblem

RFBZ

A keyed suite of Windows tools — deep cleaning, full-system optimisation, movement and macro. One pasted command installs each one.

Four tools. One licence system.

Click any product to see what is inside it, what its key looks like, and the one line that installs it. Each one has its own key prefix — a Duster key never unlocks Movement, and a Movement key never unlocks the cleaner.

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.

Fast updates

Fixes ship to the server, not to you. Running the same command again is the upgrade path, which is why there is never a version to go and download.

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 the command that installs it. The key is checked against this server every time the tool starts, so buying again is never how you upgrade — you run the command again.
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 command that has been used cannot be used a second time.
How do I remove everything?
One command removes the tools' own footprint: folders, shortcuts, scheduled tasks, the run-key entry, firewall rules, Defender exclusions and the saved licence.

Why does pasting a command trip antivirus warnings?
Because that is genuinely what a scripted install is: irm … | iex runs text fetched from a URL. Only ever paste a command from a source you trust — this page, and the links this server signs. Nothing here asks you to disable protection to install.
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.
