How to Reset / Recover Forgotten Windows Password?

Forgetting your Windows administrator login password. With no way to get into
the system, you can’t even perform basic maintenance, let alone a thorough
tune-up. Formatting is always an option, but we consider that a last resort.
(Plus, guess who’s going to have to help reinstall all the programs lost
after a wipe?) But all hope is not lost. There are a few ways to actually
retrieve a lost Windows account password. Read on, and we’ll show you the
light.

1st Method:

The first thing which you check if you forget login password. When we
install Windows, it automatically creates an account "Administrator" and sets
its password to blank. So if you have forget your user account password then
try this:

Start system and when you see Windows Welcome screen / Login screen, press
ctrl+alt+del keys twice and it'll show Classic Login box. Now type
"Administrator" (without quotes) in Username and leave Password field blank.
Now press Enter and you should be able to log in Windows.

Now you can reset your account password from "Control Panel -> User Accounts".

Same thing can be done using Safe Mode. In Safe Mode Windows will show this
in-built Administrator account in Login screen.

2th Method:

There are a lot of Windows password revealers and crackers available.

Windows password recovery tool:

but I’ve found that Windows Password Recovery Tool is the most effective.:
it not only supports XP, 2000, and NT, I have personally tested it with
Vista Home Premium and Ultimate. It works perfectly to reset any local user
account to a blank password.

Long time ago , I was confronted with the password problem. Finally , my friend Jane introduce the Windows password Reset.It helps me access windows.

I have post a solution to solve this problem. As following,

1.Download Windows Password Unlocker from Password Unlocker Official site

2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker.

3.Insert the newly created CD into the locked computer and re-boot it from the CD drive.

4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, you have removed the password.

Below is the most famous recovery tool I found:

Windows Password Recovery Tool 3.0 – it is the most popular Windows password cracker . It is a very efficient implementation of windows any versions. It comes with a Graphical User Interface and runs on multiple platforms.

Password Recovery Bundle –This is a utility to reset the password of any user that has a valid (local) account on your windows system. You do not need to know the old password to set a new one. It works offline, that is, you have to shutdown your computer and boot off a floppydisk or CD. It’ll detect and offer to unlock locked or disabled out user accounts. It is also an almost fully functional registry editor.

Windows Password Key 8.0 -It is considered as the best tool to reset local administrator and user passwords on any Windows system. It creates a password recovery CD/DVD, USB Flash Drive for home, business and enterprise. And most of all, it's the most popular and safe solution for removing your Windows password until now.

I would suggest you first try to login as Administrator how:
1- While you are on the first screen for you to log in press Ctrl+Alt+Del 2 times
2- you'll have a dialog box to type user name and password
3- type "Administrator" and leave the password blank (in case you didn't change it before)
4- Then when you log in go to "Control Panel" -> Users, and Reset the password of the other user name that you've forgotten its password

If this doesn't work please follow the below steps if you have Windows XP CD

1- Boot using Windows XP Setup CD and follow the instruction like Accepting EULA pressing F8, etc.
2- When it asks to repair your existing Windows installation, accept it and press "R" to run the repair.
3- Setup will start repairing your Windows and will start copying files, etc.
4- After a few minutes setup will restart your system and when it restarts don't press any key when it shows "Press any key to continue..." otherwise Setup will start from the beginning. Don't press any key and setup will resume where it left.
5- Now it'll start doing other tasks and will show a small progressbar with a few details in left side.
6- Look carefully at the details and when it shows "Installing devices", press <Shift>+F10 keys in your keyboard.
7- It'll open a Command Prompt window. Now type nusrmgr.cpl and press <Enter>.
8- It'll open the same "User Accounts" window which you see in Control Panel.
9- Now you can remove or reset any account password without any problem.
10- continue on with the Repair (have your Product key handy).
11- Once the Repair is done, you will be able to log on with your new password (or without a password if you chose not to use one or if you chose not to be asked for a password). Your programs and personalized settings should remain intact.
