I run three instances of Skype on my Windows 7 . I needed to autostart them fully automatically, in defined order, without need of input any usernames or passwords.

My solution is to make three shortcuts and to start all of them via batch file when Windows starts or with double click.

Shortcuts:

1. “C:\Program Files (x86)\Skype\Phone\Skype.exe” /username=yourlogin1 /password=yourpassword1
2. “C:\Program Files (x86)\Skype\Phone\Skype.exe” /secondary /username=yourlogin2 /password=yourpassword2
3. “C:\Program Files (x86)\Skype\Phone\Skype.exe” /secondary /username=yourlogin3 /password=yourpassword3
4. etc.

Batch file:

start /dC:\Users\oci\Desktop skype1.lnk && timeout 15 && start /dC:\Users\oci\Desktop skype2.lnk && timeout 15 && start /dC:\Users\oci\Desktop skype3.lnk
