Before I go ahead with an answer I'm not responsible for these actions. Since it requires to remove the password and gaining access to restricted information on the admin account. So if you get beat up by your "dad"...not my problem. But this answer could be useful to pc techs that deals with lost password on any account in Windows.
Theres a small app that I use all the time and its Offline Windows Password & Registry EditorOffline Windows Password & Registry Editor
This allows you to remove the password in the sam database on your windows installation. First you'll have to download that file and burn it on a cd or usb. If you have questions regarding burning then the instructions are on that website as well.
Boot the computer with that usb or cd you just made and after a couple of moments and lots of text (yes, its in text, no graphics or gui...just text).
Theres a walkthrough in that website but its pretty basic. here are the steps
- first you'll have to select the disk so type the number beside on the left and press ENTER
- second you'll need to select your path and registry file. Most of the time, you just have to press enter
- at this point you have to select 1 for password reset which most people use anyway.
- then you'll have to press 1 and ENTER for editing users & passwords
- Now when you'll see the table, just type in 0x%%%%. Replace the %%%% with the RID on the left side of the username. For example, if you see 3f08 beside the username
dad then you will need to type 0x3f08 and press ENTER (note: admin is always 01f4)
- then type 1 and ENTER to Clear the user password
- finally just type ! (exclamation point) and type Y to write changes to file and just reboot your computer.
AT this point the account you just reset will be blank so you'll be able to enter the account flawlessly. But again, I'm not responsible for any actions since this application used in the wrong hands can be devastating.
