Let's first take a look at where the SAM files are stored. The location of the SAM file is: C:windowssystem32configsam (as an example of system installation in C disk).
As you know, Windows XP password is stored in the system's C:windowssystem32config Sam file, the Sam file is the account password database file. When

In fact, in the new station, often because of the optimization of the excessive and lead to the evaluation period of Baidu extended, for the new station does not h

"Automaton"The function of the finite state automaton is to recognize the string, and the self-motive A can recognize the string S, which is recorded as $ A (s) $=true, otherwise $ A (s) $=false.The automata consists of the $alpha$ (character set), $state $ (State collection), $init $ (initial state), $end $ (End-state collection), $trans $ (State transfer function).The $trans (S,STR) $ indicates that the current state is $s$ and is read into a string or character after $str$ the state is reache

Friends who have used the NT kernel Windows operating system know that the management mechanism of the system password of the NT kernel is much stronger than that of the Windows operating system of the Win32 kernel, thanks in part to the guard of the NT System-SAM.
Many users have no special idea about Windows startup. Most people think about it like this: press the power supply and wait a moment, the "silly" Windows login

What is a suffix automatic machine?
Suffix automatic machine suffix automation (SAM) is an automatic machine that is constructed with the complexity of O (N) and can accept all the suffixes of a string.
It was first mentioned in Chen Lijie's Noi winter camp lecture in 2012.
In a multi-school joint training in 2013, Sam became po

All these people on the Internet are mistaken. I forgot the password of the XP system and deleted the Sam file. Then the system won't be able to access the bad things, password is required on the Recovery Console (I don't Know). There is no Sam file under the repair file (I don't know why). Why? How can we make the system better?
