I've come across the MAS activator, an open-source tool for activating Windows and Office products. It seems to offer various activation methods like HWID and KMS38. I'm curious about its safety and legality. Has anyone used it, and what are the potential risks?

Many users report successful activations using kms activator, appreciating its simplicity and effectiveness. However, some have encountered issues when attempting to link their Microsoft accounts or during system updates, leading to deactivation or other complications. Additionally, antivirus software may flag MAS as a potential threat due to its nature of modifying system files, which can be concerning for some users.​
