I have done a research
of losing Windows administrator password and find out more than 50% who have
set password on their pc will finally forget it,espercially those women,add
password to prevent their kids from downloading any games.
There are many
reasons account for this.No mather how,when you realize you have forgotten
password,you may try everthing you could do as there are many works waitting
for you.No doubt, many ways can help you remove or recover the lost password,
But here,I will show you how to delete Windows administrator
password without any software.
Boot up with DOS
and delete the sam.exe and sam.log files from Windows\system32\config in your
hard drive. Now when you boot up in NT the password on your built-in
administrator account which will be blank (i.e No password). This solution
works only if your hard drive is FAT kind.
Step 1. Put your
hard disk of your computer in any other pc .
Step 2. Boot that
computer and use your hard disk as a secondary hard disk (D'nt boot as primary
hard disk ).
Step 3. Then open
that drive in which the victim's window(or your window) is installed.
Step 4. Go to
Step 5. And delete
SAM.exe and SAM.log
Step 6. Now remove
hard disk and put in your computer.
Step 7. And boot
Start system and
press F8 key when Windows is starting up. Then select Safe Mode with Command Prompt
and enter. Choose Administrator,the default password may be blank if you don't
set the default administrator password before.Then you will enter into doc
Command as following.
Type " net user
net user xxx 12345 /add " (xxx is the locked accout name and 123456 is the new
password set on this account).Then you will see the Command Completed
Try these three
method if you do not want to download a program to recover windows password. The preconditions is you should understand
and be familiar with the operations
want to gain access to your pc in emergency,I still suggest you login to another
PC which can link to internet and download a windows password recovery software
