win7 keyboard layout change from logon screen

I am having a nightmare right now, which is I'm stuck on logon screen of windows 7 professional. My password includes turkish characters and the keyboard layout changed somehow to english. And on logon screen I can't seem to find anywhere to change the keyboard layout. Hence I cannot logon to my windows, can't use my pc.

What should I do?

I was stuck on the login screen on Windows Server 2003 while my keyboard language was accidentally changed to one that I don't have my password set in.

The solution was to use Alt + Shift to toggle between the keyboard languages.

I had a similar problem. In the end I discovered that to change a keyboard layout, you can use the (left) CTRL-SHIFT combination. To see which layout it is set to, I use the on-screen keyboard.
