Microsoft Kernel engineer Axel Rietschin answers on QuoraprofessReactOS embezzled Windows Research Kernel authorized by Microsoft for University use.
He made the above comments in 2017, butIt wasn't until recently that it attracted attention.。 ReactOS is an open source Windows compatible operating system. Rietschin points out that according to the ReactOS code tree, its internal data structure and internal function name are exactly the same as Research Kernel. He argues that ReactOS cannot be implemented solely in the clean room of public documents, and that macros, parameters, etc. are identical or similar to Research Kernel.
