If you are facing an issue with activating Microsoft Office products and are looking for a free and effective way to solve it, one common method is using KMS activation. In this article, we will explain what this method is and how it can be applied for Office activation.
The activation problem arises when Microsoft Office or Windows stops recognizing the product as activated: notifications appear, functionality is restricted, or updates are disabled. The reasons can vary—hardware changes, system reinstallation, loss of account access, key entry errors, or specifics of corporate licensing.
KMS activation is a tool for activating Windows and Microsoft Office.
This activator simulates the presence of a KMS server, making your Office product (for example, using Office KMS for activation) think it is on the network, and activates it.
The operating principle of such an activator is as follows. First, the activator installs a special KMS Client Key (Generic Volume License Key - GVLK) for your Office product. Then, it simulates a local KMS server on your computer. After this, the Office product connects to this "server" and is activated for a specific period, usually 180 days. After this period expires, the activator must run the process again.
How to Perform Office Activation Using a KMS Activator
The process of Office activation using a KMS tool may vary slightly depending on the specific activator program, but the general sequence of steps is quite standard.
Preparation
First, you need to disable your antivirus and Windows Defender. Most antivirus programs and Windows Defender recognize KMS activators as potentially unwanted software (because they modify system files related to activation) and may remove them. After this, download the activator by finding a reliable KMS activator, for example, to activate Office 2021.
