KMSoffline 2.4.3 Portable by Ratiborus

Activation is performed either from the built-in KMS-Service, or from a server on the network. The "Install KMS-Service" checkbox installs a KMS server emulator into the system; if the products contain the address "10.3.0.20:1688", the products will be activated locally from it.

Additional launch parameters (keys):
/win=act - Run the program in hidden mode, activate Windows and exit the program.
/ofs=act - Run the program in hidden mode, activate Office and exit the program.
/nosound - Run the program in hidden mode, activate without sound effects.

Setting up permanent reactivation:
In the program settings, the "Install KMS-Service" checkbox allows you to install a computer server emulator from which the products can reactivate themselves. Before checking the box, you need to activate the desired products using the built-in emulator. During this activation, the settings necessary for auto-reactivation will be written into the product. Then check the box if you want. You can check whether the activation works by performing a trial activation using the "Regular activation" item. If activation succeeds, then everything is configured correctly.

About antiviruses:
There are no Trojans in the program, but we know well how antiviruses react to activators. Therefore, it is highly advisable to add the file "C:\Windows\System32\SppExtComObjHook.dll" to the antivirus exceptions.
