Sometimes, human being is a little weird. You won’t get the thing
that you urgently need. So have a coffee, take a snap or even come back
after a few days, you may found that you suddenly ‘remember’ your
Windows password.
Method 2: Try No Password Administrator Login Backdoor
In Windows XP (not Windows Vista, Windows 7, Windows 8, Windows 8.1,
Windows 10 or later, as in these new Windows OS, Administrator account
is not enabled by default), there is built-in Administrator user
account, that has administrative credentials, enabled by default, and
without any password to protect the account from been accessed. If you
didn’t change this Administrator’s password, then try to
sign in to Windows XP without password.
Method 3: Reset password from another user account with administrator credentials
If you cannot log on to Windows by using a particular user account,
but you can log on to another account that has administrative
credentials, follow these steps on how to do the trick:
- Log on to Windows by using an administrator account that has a
password that you remember. For Windows XP, you may need to start in
Safe Mode (initiate by pressing F8 during bootup).
- Click Start, and then click Run.
- In the Open box, type control userpasswords2, and then click OK.
- Click the user account that you forgot the password for, and then click Reset Password.
- Type a new password in both the New password and the Confirm new password boxes, and then click OK.
Method 4: LOGON.SCR password reset trick
LOGON.SCR changing administrator or domain admin password hack works
on Windows NT 4.0 and some versions of Windows 2000. The simple trick
uses Cmd.exe (Command Prompt) as screen saver that triggered by system
when idle, allowing users to
access to command prompt as screensaver to change password.
Method 5: Do-It-Yourself (DIY) third party recovery tool
There are a lot of tools and utilities that can be downloaded and
used to recover, reset, retrieve or reveal existing password. These
password reset or retrieval utilities, free or paid, are usually a Linux
boot disk or CD that able to comes with NT file system (NTFS) drivers
and software that will read the registry and rewrite the password
hashes, or can brute force crack the password for any user account
including the Administrators. The advantage is that there is no fear of
leaking your password to outsiders, while the process requires physical
access to the console and a floppy, DVD or CD drive, or USB port with
USB flash drive, depending on which tool you choose. And it’s not easy,
although it always work!
Offline Windows Password & Registry Editor
(also known as Offline NT Password & Registry Editor) – Available
as bootdisk or bootable CD or USB Drive image which contains things
needed to reset the passwords on most systems, Offline Windows Password
and Registry Editor works to change or reset password of any users on
32-bit (x86) and 64-bit (x64) Windows NT 3.51, Windows NT 4, Windows
2000, Windows XP, Windows Server 2003, Vindows Vista, Windows Server
2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012,
Windows 8.1, Windows Server 2012 R2, Windows 10, Windows Server 2016 or
possibly later. It can also detect and offer to unlock locked or
disabled user accounts.
Offline
Windows Password & Registry Editor does not support EFS encrypted
files. If password is reset on users that have EFS encrypted files, and
the system is XP or newer, all encrypted files for that user will be
UNREADABLE and cannot be recovered unless you remember the old password
again.

Ubuntu Live CD, where you can boot up to a Linux desktop or terminal,
then edit or reset the password for user account with “chntpw -i sam”
where sam is the sam file copied from %WinDir%/System32/config folder.
chntpw is included in many Linux distributions, or available for repository. Alternatively, search for it

Cain & Abel
– Cain & Abel is a password recovery tool for Microsoft Operating
Systems. It allows easy recovery of various kind of passwords by
sniffing the network, cracking encrypted passwords using Dictionary,
Brute-Force and Cryptanalysis attacks, recording VoIP conversations,
decoding scrambled passwords, recovering wireless network keys,
revealing password boxes, uncovering cached passwords and analyzing
routing protocols. The program does not exploit any software
vulnerabilities or bugs that could not be fixed with little effort. It
covers some security aspects/weakness present in protocol’s standards,
authentication methods and caching mechanisms; its main purpose is the
simplified recovery of passwords and credentials from various sources,
however it also ships some “non standard” utilities for Microsoft
Windows users.
This tool needs to be installed, so you must have another working
computer to recover your password remotely. Thus it’s likely to be
useful for system administrator only. Supports Microsoft Windows 2000,
Windows XP, Windows Server 2003, Windows Vista and possibly all later
Windows OS.
Hash Suite
– Hash Suite is a Windows program to test security of password hashes.
It’s primarily a tool for system administrators, security personnels and
security consultants to audit large sets of password hashes to identify
weak passwords but password recovery is a possible secondary use.
Hash Suite is able to import local and remote accounts with
administrator privileges without reliance on any additional tools.
However, the free version of Hash Suite does not support import of
remote accounts, but you can also use one of the many pwdump tools to
obtain the password hashes. This requires either administrator
privileges or reboot from a CD that will access the hard drive directly
(bypassing the installed copy of Windows).

Method 7: Bypass Windows log on password with DreamPackPL
DreamPackPL
allows users to skip or bypass Windows login security in Windows XP or
Windows 2000, and log on to a password protected Windows user account
without a valid password or the need to change the existing password.
Warning: If you change or reset password by using any method above,
all EFS encrypted files in Windows Vista or Windows XP will be
unreadable and no longer recoverable unless you remember the old
password that used to encrypt the files. So if you have any encrypted
files, it’s best that you try to crack the password first in order to
retrieve and get back the existing password first, before you attempt to
reset the password to a new one.
