What is the Office: Ohook activation method?

The Ohook method is an activation technique integrated into the open-source Microsoft Activation Scripts (MAS) script, enabling various versions of Microsoft Office to be permanently activated on Windows 8 and later, with the exception of Office 2010 and Office UWP applications.

This method works offline and survives Office repairs and updates as well as major Windows upgrades, eliminating the need for reactivation in these cases.

Ohook works by installing a customized version of the sppc.dll system library in the Office directory, without modifying existing system files. This custom library intercepts Office activation requests and returns a response indicating that the product is activated.
