Breaking Windows 2000/2003/XP/Vista Administrator Password
ADVERTISEMENTS
Going by my word posting here about a simple tool which will break Windows 2000/XP/2003’s Administrator account’s password.
Before starting, for newbies…
Windows NT 5.0 = Windows 2000 (all edition)
Windows NT 5.1 = Windows XP (all edition)
Windows NT 5.2 = Windows 2003 (all edition)
So throughout this post I will refer our target as Windows NT 5.x (as following content are equally applicable to all Windows NT 5.x OS family).
So lets start the fun…
You will be surprised to know that you can break into any Windows NT 5.x system without any software tool 80% of the time! For rest you need a software like below!
First lets get to 80% of the vulnerable system….
In Windows NT 5.x, you can create any no. of user with different names, privileges and optionally password.
One such account with highest privilege level, with user name “Administrator” is setup by default.
At the time of installation Windows NT 5.x prompts for password but many systems are setup by vendors and other person. The end-user of this system is different than one who installed it. These lazy people are always in hurry and often left this password as blank.
The irony comes next. In final step of installation you create an account with mostly your first name. Lock it with password(optionally) and start using the system. Now on welcome screen you see account(s) with different name. But have you never see this default “administrator” account unless you boot in “safe mode”.
Now if you can’t see “administrator” account on screen (as with Windows XP login default screen), just press “CTRL+ALT+DEL” and it will change login “screen” to login “box” where you can type “administrator” as user name! This is what works 80% of the time.
Now for rest of the 20% system….
There are literally more than 100’s of tool available on Internet and the tool I use is a small Live-CD named ntpasswd created by pnordahl. I got it from my hacker friend Surun.
Burn this ISO on a CD. Its bootable image of approx 2.7 MB.
It has Linux OS with text-mode only. No Linux Knowledge Require here to use this disk. 
After booting from CD. A menu driven program will start with options and their description at each level.
READ EVERYTHING BEFORE GOING AHEAD as one mistake may make the target machine unusable.
One mistake may crash the system to the reinstallation phase! So test it first on systems from college, office, etc!
It worked 100% of the time….
As its 3.03 MB (after extracting) you can burn it on a mini-CD and keep it in your wallet all the time, so can roam around having master key to all systems having Windows NT 5.x family OS!

@Anonymous
I found official help page for this! Hope it will help you finally!
I tried with DELL D630 Laptop
OS: Windows XP pro
After booting …it shows
“Please select partition by number or
a = show all partiotions, D = Automatically load new disk drivers ….
I have seleted the “a”….
but nothing showing …it showing above options once again…..
finally…i couldnt chage my laptop admin password….
@Just
Did you tried another option - to press D.
The menu comes when the program in disc fails to locate your hard-drive time.
Technically it uses old linux kernel which may not be compatible with new hardwares.
If you have knowledge of hardware/linux, the you may try to load hard-disk driver manually. But DO IT ON YOUR RISK as it may damage the whole system.
I downloaded the winpass.rar and unpacked it. In it there was another rar file. After unpacking, it revealed somefiles with funny names like ascii characters. I bunred that to CD but it didnt BOOT. Now what.
@Sheraz
In winpass.rar there is a ISO file. It seems ISO files are by default associated with winrar application on your system.
You need to use Nero like software to burn ISO file so as to make bootable CD.
Here you seem to create a Data CD. It won’t work…
plz rahul could u send me the link for downloadin the zip file coz i downloaded it but it’s comin with .txt
so wat to do in this case or plz forward me that file to ma email
thankin youuuuuuuu
@Humash - Just updated this post with new links. Please check again.
Hi,
Does this work on Xp SP3? I wrote a small “OS” in ASM and C++, that did the same, but that stopped working with SP3.I never made that public as I feared script kiddies misusing it.
Hint 1: Basically, there are certain commercial apps available, which infact are even supported by Micro$oft!!
Hint 2: Recovering or resetting the Xp password involves a kernel specific file,which cannot be modified unless you have full Ring0 mode(protected mode).
These two hints and google will help anyone who wants to break XP password for any user.But yea, with SP3 there are certain changes, which I have not looked into.
@Aditya
It work on Vista as well and it is continuously updated so try it…
