How to hide duplicate active program in the taskbar?

Question

Windows

I asked this question, googling found only a few suspicious programs. Didn't check. Recommend something?
And I need the program to be in fact in 2 windows, and the taskbar reflects the opening of one. colorless... It doesn't matter in the dispatcher, no one checks it.

Answer 1

Hide the window with any adequate automator. For example ncron . An example of two tasks for hiding and showing a window:

#( win_hide
WatchHotKey: "1"
Action:
    WIN-HIDE: "*Notepad*"
)#
#( win_show
WatchHotKey: "2"
Action:
    WIN-SHOW: "*Notepad*"
)#
