How to create a borderless window with titlebar in windows c++

I am trying to create a Direct3D app that is operating in windowed mode with a title bar and minimize/quit button. However, I'd really like to be able to axe the border around the window.

I am looking to do this because it looks pretty cheesy on dual monitors when the app is filling the primary monitor horizontally (with room to move the app vertically), but its window border overflows onto the secondary screen. I've tried a bunch of combinations of setwindowlong with GWL_STYLE and GWL_EXSTYLE, but can't seem to make headway unless I disable the title bar.

I've seen a bunch of apps that are borderless however they seem to emulate the title bar rather than using the built in one provided by Microsoft.

Thanks for any suggestions.

You can't remove the border and keep the titlebar AFAIK.

You can reimplement the titlebar by using WM_NCHITTEST but you still need to draw it yourself which would not be a bad idea if you want your D3D app to look its best.

Visual Studio, last time I checked, achieves its border with transparent layered windows standing behind the primary one. They are the shadows you see.
