Ratiborus KMS Tools
A portable collection of activation utilities for Windows and Office bundled into one launcher, updated regularly against current builds.
About Ratiborus KMS Tools
KMS Tools is a launcher wrapped around a set of separate activation utilities, kept in one place so nobody has to go collecting them individually. Each tool inside targets a different scenario, and the launcher lists them with a short description so the right one can be picked without guesswork.
The collection covers both Windows and Office across a wide range of releases, from older builds still running on legacy hardware through to the current desktop and suite versions. Because the launcher is portable it runs from the extracted folder with no installation and leaves nothing behind when the folder is deleted.
Alongside the activation utilities the package carries a set of practical helpers: a status checker that reports the current state of a system, a converter for changing between retail and volume channel installs, an Office installer and downloader, and a cleanup tool for removing previous keys and configurations before a fresh attempt.
The package is refreshed frequently, which is the main reason people track it rather than keeping one old copy. Each release folds in fixes for changes in current builds, and the included readme lists what changed since the previous version and which utilities were updated.

Installation walkthrough
These steps assume a clean machine. If a previous release of the same application is present, deal with that first, since an overlapping install is the most common cause of a setup that stops halfway.
- Turn off real-time protection completely before extracting, since tools of this type are always flagged on heuristics.
- Extract the whole folder rather than running the launcher from inside the archive.
- Run the launcher as administrator.
- Read the included readme and pick the utility that matches the target release.
- Reboot after the tool reports completion, then check the status with the included checker.
