It mostly comes from feeding SdbTagToString all valid inputs. Some constants are from msdn. I do not know of a *real* program calling this API other than winapi itself. kernel32 uses it for backwards compatibility. I wrote plenty of tests[1], parsed shim database files (C:\windows\AppPatch\*.sdb) and matched an entry in datatabse with executable[2] (Yes, I know [2] is done wrong but that's my dirty working branch)

Where all of this comes from? Is there an application that calls
apphelp APIs and doesn't work because of failures? How are you
testing your implementation?
