Get the scaling percent in windows

We can get the screen size using the following MFC code;

GetWindowRect(GetDesktopWindow(), (CRect)rect);

And we can change the screen scale using the windows Settings --> System --> Display --> Scale and layout --> "Change the size of text, apps, and other items" . This ComboBox includes 100%(Recommended), 125% 175% etc.

When I changed to 125% or 175%, I cannot get the correct screenshot. The sceenshot will be cutted.

How can i get that screen scaling value, or how can i get the correct screenshot at all the time?

Perhaps this is due to DPI virtualization which normalizes coordinates by default so that apps don't need to be aware of scaling.
