Reset Open File Dialog Position in Windows

I open an open file dialog using GetOpenFileName function. I'm making a handler function that will center the dialog window inside the owner window. I center the dialog on CDN_INITDONE notification.

Currently, it seems that Windows remembers last dialog position for desktop apps and overrides my dialog coordinates. How to reset that last remembered position so that I can check centering will work for my users?

I thought about running a test using a different user or virtual machine but this isn't very convenient. Unfortunately, searching in the registry for myexecutable.exe returns nothing.

I'm running Windows 8.

I'm about a year late, but I just had to deal with this issue. What worked for me was supplying an OFNHookProc to GetOpenFileName(), then subclassing the parent of the HWND passed to the OFNHookProc.

After subclassing, I handle WM_WINDOWPOSCHANGED, and if the coordinates aren't where I think they should be, I do a SetWindowPos(), undo the subclass and return 0.

Edit: I should say that other methods, such as WM_INITDIALOG in the hook proc or CDN_INITDONE did not work for me whatsoever.
