What’s included in your Office 2016 Pro Plus license

Your purchase includes one Microsoft Office 2016 Professional Plus activation key for one Windows PC. The key is unused and activates through Microsoft’s official servers. Important: Microsoft Office 2016 reached full end of support in October 2025 with no extended security updates – unlike some other Microsoft products, there are no further patches of any kind planned for this version. The software continues to function normally on your PC, but will not receive any future security updates. If security patching is a requirement for your environment, we recommend considering a newer version instead.
