I found the
KMS activation tool , where various activators for Windows and Office are collected — KMSAuto, KMSpico, Microsoft Toolkit. They work through KMS technology, which was originally used for corporate activation. There is a step-by-step instruction of four steps: I selected the activator, downloaded, launched, and rebooted the computer. The description says that the programs work offline, do not collect data and have an open source code — you can check for malicious functions. At the bottom of the page there are user reviews for February 2026, most of them say that everything is working.
