A friend of mine had, while trying to learn computer hardware, had entered cmd from windows 7 and thereafter entered as under cmd + and some password and then entered. Due to this, he lost his access to the computer because it simply keeps asking for password.
He could not explain to me the correct thing he entered but some thing like "cmd+...". How to come out of it?
Thanks to all who try to understand my problem and try to solve it.
