About this release
KMSAuto++ is a portable activation front end that automates the key management service model Microsoft built for large organisations, but runs the whole thing on the single machine in front of you. It installs a generic volume key, points the licensing client at a service hosted on the loopback address, and lets that service answer the activation request the way a corporate server would. The result is a system that reports itself as licensed without a phone call to anyone.
The tool leans on a small scheduled task that renews the state on the usual cycle, so the machine stays in an activated condition rather than lapsing after the first renewal window. That renewal piece is the part people care about, since a one time activation that expires again in a fortnight is not worth much. The interface exposes the renewal task, the installed key, and the current status in three plain tabs.
Everything runs from a single unpacked folder with no setup wizard, which is why it stays on so many technician USB sticks. It covers the volume licensing editions of the desktop operating system and the perpetual Office suites, detects what is present, and picks a matching generic key on its own. Manual controls are there under an advanced tab for the cases where the automatic pass picks the wrong edition.

Installation notes
Follow these in order. Most reports of a failed install come from skipping a step rather than from the package itself.
- Disconnect from the network before you begin.
- Turn off real time protection, since activation tools are flagged on sight by design.
- Extract the archive to any folder you like, no installation is needed.
- Run the executable as administrator.
- Pick the product, run the activation, then create the renewal task when prompted.
- Close the tool and reconnect to the network.

Things worth knowing
- Real time protection will quarantine the executable the moment it lands, add an exclusion for the folder first.
- The retail editions of Windows and Office are not volume licensing products, this tool targets the volume editions.
- Leave the renewal task in place, deleting it lets the activated state lapse at the next cycle.
Questions about this title
Does it need an internet connection?
Will the activation survive a reboot?
Why does my antivirus delete it?
Does it work on the retail edition of Office?
What people are saying
Does exactly one job and does it cleanly. Renewal task is the part that matters, set it and forget it.
Antivirus ate it on first extract. Folder exclusion sorted it, then no trouble.
Detected the Office edition correctly on a machine where the last tool I tried picked the wrong one.
