How to autostart Skype minimized?

DM2Portable or RBTrayPortable are apps which can minimize apps on system tray.

Write a simple script which is like:

E:\PortableApps\DM2Portable\DM2Portable.exe -E:\PortableApps\SkypePortable\Skype.exe

and put it to your StartMenu-->Programs-->Startup folder.

But first you need to check command line parameters of these DM2Portable or RBTrayPortable.

If I recall correctly, Skype did not have this feature in options (though it should). And you can't create a shortcut to SkypePortable.exe and set the shortcut to start minimized as Windows will only apply it to a window spawned by the first process (skypeportable.exe not skype.exe).

I think there may have been a command line option to pass to Skype to get it to start minimized but it was ignored when Skype was set to run from USB due to a bug in Skype. I'm not fully sure about that thought as it was a while ago. Some Googling and experimentation with a SkypePortable.ini should determine that. I'm not quite up for checking myself yet, though.

Can I run Skype for Windows desktop from the command line?
Windows

You can run Skype for Windows desktop from the command line. For example, if you have installed Skype in the default location, type the following command (including quotes):

"C:\Program Files\Skype\Phone\Skype.exe"

You can also supply the following arguments:
Command Description
/nosplash Do not display splash screen when Skype starts.
/minimized Skype is minimized to system tray when it starts.
/callto:nameornumber Call the specified Skype Name or phone number.
/shutdown Close Skype.
/secondary Allows you to start an additional skype.exe instance.

For example, the following command will close Skype:

"C:\Program Files\Skype\Phone\Skype.exe /shutdown"
