Change input language in login screen

Question

My windows has 4 input languages, I have set the administrator password in a language other than English (the default language). Now I'm not able to login to my account as I'm not able to change the input language in login screen. I'm opening 'On Screen Keyboard' and I'm pressing Alt+Shift keys but the input language doesn't change. How should I change the input language in the login screen?

All answers I found including what jet offered as duplicate (Change Windows 7/8/10 system language - welcome screen, login, etc) is involved accessing control panel and changing some settings while I'm stuck in login screen and can't move any forward

Solution

I was not able to enter password (that I knew) because the the password was in another language and I wasn't able to change the input language. I finally ended up changing my password form another PC, using this program:

There were lots of programs but this one worked like a charm.

Possible duplicate of Change Windows 7/8/10 system language - welcome screen, login, etc. And it already has answer.

@Jet the question you mentioned is involved using control panel and changing settings while I'm stuck in login screen and can't move any forward

Try to reset your password, howtogeek.com/96630/…

@Jusup resetting password is possible if you have already created a password reset disk. however I knew the password but was not able to type it as I was able to type it without changing input language. I finally managed to change the password from another pc

@AshkanMobayenKhiabani You should convert your comment into an answer. Please read Can I answer my own question?

@DavidPostill I know I have used stackoverflow a lot and answered my questions several times, actually I didn't do that because the way I recovered the password is not the answer to my question (which was changing input language on login screen) however I do that in case one wants to change the input language for the same reason
