KMSAuto is a utility that helps you activate Windows and Office for free, bypassing the purchase of license keys. This program will help you recover the lost keys from the Windows operating system.
You do not need to have the knowledge of a system administrator to use the activator. In this article, there is a simple instruction that will clearly show how to use kmsauto as a Windows 10 activator.
You can also extend the trial period of using Microsoft Office indefinitely. You can also activate the server versions of Windows. You can read more about everything below. If you are already familiar with the activator, you can simply skip the entire article and proceed to downloading kmsauto.
The download button is located a little lower, if it does not enter the screen, then scroll the page.
How the KMSAuto activation program works
You still decided to read the article in full, then I will describe to you the principle of operation of kms activators. Like all similar activators (kmspico, kmsnano), kmsauto manages the license keys of Microsoft products through a virtual kms server.
You no longer need to constantly search for temporary activation keys on internet forums. Activation using an automatic activator occurs once and for a long time. Until you decide to cancel activation and delete the server from your PC.
A virtual server (kms server) stands in the way of data transfer between the Windows client or the Office. Then he accepts all the data and signs the license as official. This is how all activators that work according to the kms principle are arranged.
I noticed that most of the free builds of Windows on the web already contain a kms activator inside. That is, after you download the free Windows 11 or Windows 10 and install it on your PC, you can find a folder with an activator and an installation on your desktop.
Download kmsauto
In order to download the archive with the activator, you need to click on the download button. Next, you will be redirected to the download page. The archive will appear in the download package that is configured in your browser. Alternatively, you can save the activator to any location. It is not necessary to unpack the archive, the program can be run from the archive.
Risks of use
If you decide to activate your Office or Windows to bypass the purchase of license keys and choose the KMSAuto program, then it’s worth talking about the risks. The first and most important risk is the reliability of the source from where you download the activator.
To do this, you need to carefully select a resource from a variety of sites in the search results. The main thing I pay attention to when I download a program from the Internet is reviews. Every reliable website should have reviews from the users of the website. It is advisable to read these reviews and make sure that they were written by real people and not bots.
Then, after you download the activator, you should check it for Trojans and viruses. To do this, I check the exe files in online services. But please note that any activator is an unwanted program, kmsauto will always arouse suspicion from antiviruses. But this does not mean that the program contains Trojans and the like. Analyze antivirus reports.
Description of Kmsauto modes
The activator has several activation modes. These modes are designed for different users. We are talking about ordinary users and advanced ones.
- The most common activation mode is automatic. Our activator selects the activation method itself, depending on which program needs to be activated. It’s hard to make a mistake in this mode. It is used by 99% of users. Even if an error occurred during activation, kmsauto will repeat the activation procedure again.
- Manual activation mode. In this mode, the user must configure everything himself. If you are interested in this mode, then you understand everything and are an advanced user. The manual mode also includes many settings. For example, you can change the build version of your Windows operating system.
CMD activation mode
The program also works from the command line. Here is a description of the basic commands to run from the command line.
KMSAuto.exe /win=act # Activates the Windows operating system.
KMSAuto.exe /off=act # Activates the installed Microsoft Office package.
KMSAuto.exe /log # Includes logging of the activation process.
KMSAuto.exe /task # Creates a task in the Windows Scheduler.
KMSAuto.exe /key=xxxx-xxxx-xxxx-xxxx-xxxx # Sets a custom product key before activation.

KMSAuto.exe /silent # Runs the program in silent mode, without displaying the graphical interface.
KMSAuto.exe /uninstall # Deletes the activator and all related files and records from the system.
KMSAuto.exe /help # Displays background information about the available commands.
