My friend has a windows 7 laptop. it change his user account's password to new password by none-english characters. Then remove that language from language Keyboad. now when he try to login to his account, he can't type his password. I can't find 'switch user' link on windows login screen, to use his administrator account. also when I try to use safe mode, still it ask for his current user password and can't use default administrator account. Is there a way to add a language to Language input on windows login screen without login to windows ( and using control panel , regional and language option)? Is there any way to switch use while there isn't switch user link?
