## What it is
ohook is a C-written hook library that masquerades as the Office sppc.dll to intercept the SLGetLicensingStatusInformation license check, enabling full functionality of Microsoft Office subscription editions without a paid license. It is distributed primarily for use via activation scripts from its partner site massgrave.dev.

## Use cases
- activate microsoft office subscription editions for free
- bypass office license check on windows
- make office 365 apps fully functional without subscription
- hook sppc.dll licensing status function
- fix office license status banner errors

## When to choose
- you need full feature parity of subscription Office editions rather than partial Mondo-license KMS activation
- you want a lightweight DLL-based hook instead of KMS emulation

## When to avoid
- you need a legally licensed Office installation
- you require vendor support or documentation beyond the minimal README
- you are not on Windows with Click-to-Run Office

## Facets

- maturity: active
- function: security, middleware
- domain: windows, developer-tools
