HotkeyToWindow.exe Assigns a hotkey to a window. When pressed will activate that window.

This uses the inbuilt compilers in Windows 10 - there are three VB.NET compilers and three C# compilers - just copy each text file into the same folder and double click the batch file to make the program.
Window Manipulation Posts

There are two types of hotkeys in Windows. RegisterHotkey requires a program to expect it. WM_SetHotkey is supported by the default behaviour of a window so the program doesn't need to be aware of it.

Hotkeys are system keys so work all the time. To take the example below, using sendkeys to send Ctrl+N to any application will activate Notepad. This is one way around restrictions on setting the active window.

REM This file compiles TopMost.vb to TopMost.exe
REM HotkeyToWindow.exe sets a hotkey to activate the window
REM To use 
REM     HotkeyToWindow &ltModifier&gt  &ltvirtualkey&gt &ltWindowtitle&gt
REM E.G.
REM To assign Ctrl (2) and N key (78) to notepad
REM     HotkeyToWindow 2 78 Untitled - Notepad
REM To remove the hotkey send 0
