How to connect multiple VPNs using OpenVPN on Windows 7 on the same time

How to connect multiple VPNs using OpenVPN on Windows 7 on the same time :-

you will need to create some additional TAP-WIN32 adapters if you haven't already.

If you are using OpenVPN 2.3.x or later, run addtap.bat:

C:\Program Files\TAP-Windows\bin\addtap.bat

If you are using an older version of OpenVPN, run the tapinstall command

C:\Program Files\OpenVPN\bin\tapinstall.exe

C:\Program Files (x86)\OpenVPN\bin\tapinstall.exe

(NOTE: Maybe you should open the cmd with Administrator Privileges)

The easiest way, not to mention tapinstall.exe, is to run Start > All Programs > OpenVPN > Utilities > Install > Add a new TAP vitrual ethernet adapter

Please remember to run it with administrator privileges, in other case you will just get tapinstall failed.
