I was initially skeptical about using an activator, but KMSAuto
https://kmsauto.org/ proved to be both reliable and safe. I activated my Windows 11 and Office 2021 without any issues. The site provided detailed instructions on disabling antivirus temporarily, which made me feel more comfortable. Since then, my software has worked flawlessly, and I haven't faced any activation problems. This is a trustworthy tool for anyone looking for a secure activation method.
