KMSAuto++ 1.8.3 Stable Portable by Ratiborus

Features :
— Keys are installed only on non-activated products.
— If "Force installation" is selected, the keys are installed on all products, including activated ones.
— On the "Settings" tab you can specify the external address of the KMS-Service. The service built into the program will not start when activated. If the activation error is 0xc004f074, make sure that your firewall does not prohibit connections to your KMS-Service.
— Create a task in the scheduler to reactivate Windows (there is a special tab in the program for this), after which the program itself can be moved wherever you want, you can even delete it completely.
— The program does NOT require any version of the .NET Framework.

Installing KMS-Service
On the "Settings" tab, you can install KMS-Service in the system, Windows 7-8 will be able to activate from it independently, with appropriate settings, at 127.0.0.2:port, and any systems and offices can be activated using your network address.
The installed server does not conflict with either the task in the scheduler or with manual activation using the "Activate Windows" and "Activate Office" buttons. If your system is 8.1, a special driver will be installed during activation, which will be removed after activation is completed. To do this, "== Integrated KMS-Service ==" must be set in the settings.
You can also configure activation from an external server; when activated using the buttons in the Main window of the program, your system settings will not be changed, they will be restored immediately after activation.
Using the two buttons at the bottom of the Settings window, you can view the log file of the running server.

But nothing is activated for me!!!
Perhaps your product is not VL, is not intended for activation from KMS-Service (Windows 7 Ultimate program DOES NOT ACTIVATE), or your antivirus is blocking activation.
The program does NOT require any version of the .NET Framework.
