Principle of operation

Office hacking software emulates interaction with a KMS server, which checks the software license and confirms or denies it. The application does not even require the presence of the Internet.

You can use KMS to activate Office in different ways

  • a special service that simulates a connection to a KMS-server;
  • using virtual modified files instead of system ones, in which no changes occur in the real files of the operating system.
  • using a license key and a special driver;
  • activation using a manually set code.

By default, the application iterates through these algorithms until it achieves a solution to the problem, and remembers the successful one. The user can specify any method manually in the “System” tab.

Modules and utilities

In the form of separate modules, the KMS activator includes tools such as:

  • Office C2R License Setup – removes and installs licenses;
  • Office C2R Install is a utility for downloading and installing the specified office applications with their subsequent activation;
  • program for validation on the Microsoft website.
  • The MSActBackUp utility is available to save the current activation state to a file. Also, a converter is built into KMS that can convert the version of any office program from RETAIL to VL, because the activator only works with the latter.
