Peter,
What I did is this:
-
Settings in eM Client: run on system start and minimize to tray
-
I deleted all shortcuts wherever I had them
-
Restart, brought up the program in full screen, closed the program
-
Then I created a shortcut directly from the program (eM Client.exe), and placed that on the desktop, settings “run minimized”. Clicking on the desktop icon brought up the program minimized to the tray/ taskbar
-
Restart, brought up the program maximized
-
Put the desktop icon on the start menu screen. Clicking on it brought up the program minimized to the tray/ taskbar
-
Restart, again brought up the program maximized
Apparently, when I created the desktop icon shortcut, the program automatically put the shortcut in C:\Users\User name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
So, I think for the time being it is possible to run the program minimized only by clicking on the shortcut, at startup/ reboot it runs in normal screen.
BTW: I use Malwarebytes and, of course, Windows Defender.
Best,
Danker
