If you are system administrator then you must know how to change forgotten password or unknown password on Windows OS. In this tutorial i will show you how to do that.
First you need bootable CD/DVD or USB to start Windows with it. Then, when your system installation start press Shift + F10 which will take you directly to Command Prompt ( cmd ) like on image below.
When we finished this step, we need to check on which drive letter is our system. This will do with typing
list volume and check all partitions. When you check what is your system drive letter, type
exit and go to the next step.
Now we need to copy sticky keys from your system parition to
C:\ to create backup. Then repleace
C:\Windows\System32\sethc.exe . This part is important. To complete this part see image below and follow the code.
Now we need to reboot computer and wait for system boot up. When the system load to the users screen just press 5-6 times Shift and you will start sticky keys which we earlier replace with cmd ( see image below ).
In the Command Prompt typing
net user and hit Enter. On the screen you will see all user on the computer. Then you use command
net user <username> <new password> to change password. In some case you can create administrator user if is not exists and then you can manage with all users on the computer.
That is it, if you have a questions or suggestions just write the comment and i will review and answer on that.
