CMD+Space not working to switch language.

My parallels is version 10
"CMD + Space" shortcut is not working to change language in windows 7 login screen, i need to type my password and i can't because the current keyboard language is in Arabic and the password is in English.

Whenever i try the shortcut nothing happens but i am sure %100 that the keys are "recognized" to the virtual machine.
"CMD+Space" shortcut is also grayed out in the shortcut options.

I have tried several solutions but nothing works, i have tried to change a line of code int eh config file inside the PVM folder, i have checked that CMD +Space is not used for anything else rather than language switching, i followed some tutorials on parallels website but with no luck , i even tried external keyboard to switch language and re-installing parallels tools.

Please any help would be appreciated i can't login into my windows 7 virtual machine!
even a solution to remove that password so i can login into windows 7 (switching was working inside windows 7 before that problem occurred)
Update: even copy and paste shortcut is not working!

 

In order to resolve the issue unable to change keyboard input language using CMD+Space, please follow this steps suggested and how it check it works.

 

thank you for fast support but i have already tried that with no luck, all i want is just remove that password, write in English or even copy and paste it from mac OS or otherwise i will have to re-install windows 7 and lose all my data and software's
