Frequently Asked Questions (F.A.Q.)

I will try to answer some questions and help you.

🤓 How Windows 8 KMSAuto Works?

A real KMS sends a serial verification request to a Microsoft server. But in our case, everything is a little different. The activator simply emulates this “remote” server on the client computer. Accordingly, the system “thinks” that it has contacted the official KMS server directly. Next, the key is installed in Windows, the system thinks that it has received the key and starts working.

🤓What is KMS (Key Management Service)?

The KMS (Key Management Service) server allows you to activate corporate versions of Windows within the network without the need to connect to the MSFT activation center via the Internet or by phone.

🤓 What to do if the Antivirus swears?

KMSAuto activator does no harm, but still antiviruses swear at it. And also in every possible way block its launch. I will say the same about Windows Defender, he also categorically does not accept the activator. If you try to run the activator with the antivirus enabled. Then he will simply delete it and nothing will be activated.

To run the activator, turn off the antivirus or add it to the exception. Do the same with Windows Defender.

🤓 How to delete KMS Activator?

This activator is not installed in the OS, but is portable. So delete nothing. Just select the folder with the activators and click the “delete” button.

Sometimes unsuccessful attempts to activate Windows may require you to delete the KMS-Service itself and the license information. To do this, follow the instructions below.

  • To clear the system from previous keys, switch to the “Utilities” section and select the “Reset Invalid System Status” button. All files containing license information will be deleted.
  • To remove the server, on the System tab, select Remove KMS-Service. Now you can try to activate it again.
