Hi Alex,

Oh I wasn’t aware of that, that’s great.

Thanks for the tip 😊

Hey Ged,

The full internal internal filter manager header was published by microsoft in the "minwin" folder of the TH1 and TH2 WDK+SDK. Same place where Timo and Thomas have been using "ntosp.h" from.

Best regards,
Alex Ionescu
