How to determine whether a physical page has been modified

Hello,

Does anyone know of a supported way to determine whether a physical page in memory has been modified? To my knowledge, the modified flags reside in PFN database entries and I am not aware of any APIs that expose the PFN database.

Thanks,

kdev

There is no supported way, I’ve looked at this for a product idea for years
and spoken to people in Microsoft about it. You are not going be able to
get this info.
