How to run a 16bit Windows application on Windows 7 64bit with window integration in the host system?

Question

linux

Task:
Run a 16bit Windows application on Windows 7 64bit in such a way that the application window behaves in general the same way as in the native system?
Problem:
Windows 7 removed support for 16-bit applications.
Obvious solution:
Using virtualization. For example DOSBox, VirtualBox, etc.
Solution flaw:
The application window will be limited to the VM window and will not scale well, it will be inconvenient to switch between it and other windows of the host system.
Questions:
1) Is there a way to somehow integrate a window from the guest system into the host system?
2) It seems that there were some projects to integrate individual windows of applications running under * nix into the Win system. Does anyone know what they are called?
Note:
The original application was written under Win 3.11. Works great in WinXP and under Wine. No special drivers are required.

Answer 1

The obvious solution is Windows XP Mode. The most convenient integration of VM into the system. You can distinguish a VM window from a host window only by color design.

Answer 2

In general, the same Wine, it seems, is also ported to Windows: sourceforge.net/projects/wine/files/Win32%20Packages/

Answer 3

If in virtualbox a 16-bit application only runs in full-screen mode, then display integration mode will not display this application. In this case, the scaling mode (Host + C) is suitable - the window becomes “rubber”.

Answer 4

Maybe try?..
VBoxHeadless --startvm "%имя_машины%"
