Please use the following method wisely. The tutorials are fairly simply, it does not require an intensive knowledge in computing to go about recovering your lost password.
Method 01 – Ophcrack Windows User Login Password Cracker
Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman’s original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.
What makes ophcrack so powerful is the ability to crack Microsoft Windows user login password with the LiveCD function, no installation needed. LiveCD boots up before windows does, thus allowing it to load and starts cracking your Windows XP and Vista login password, this bootable feature makes sense because without your password you are completely log out of your own computer.
The only drawback of the cracker is when it comes to cracking passwords with alphanumeric more than 15 characters, fear not, the good news is, how many people actually have a 15 character password? Probably that is why you’re reading this post because you have a password that is so long that you’ve somehow forgotten about it, am I right? Anyway the software is free and here are some of the unique features.
- Runs on Windows, Linux and Mac OS X.
- Loads hashes from encrypted SAM recovered from a Windows partition.
- Bootable directly from the CD.
Note that the it only runs on Mac powered by intel processor, older Macs powered by Motorola G5 processor are not compatible.
Method 02 – Administrator Mode
The next scenario: What if you lost your Bios password and you’re not able to change the boot up sequence from Harddisk to CD-Rom, thus rendering LiveCD feature useless. Fear not, all Windows comes with the Administrator function, the question is, how do we bring up the administrator login screen?
Simple, hit ‘Ctrl’ + ‘Alt’ + ‘Del’ to bring up the alternative login screen, a new dialog box would popup, what you need to do is key in the user name as ‘administrator’, leave the password field empty and hit ‘enter’. Volla, you’re log into the default administrator user account. Run ophcrack to retrieve your forgotten Windows Login password.
Method 03 – Repair Windows
This method requires the original Microsoft Windows CD, TechTrax has an article ‘Forgot My Administrator Password!‘, they provide a step by step tutorial on how to recover your lost Windows XP password.
