How to recover your Windows 7 password when you forgot it?
This step-by-step article shows you how to recover your forgotten Windows 7 password, plus an alternative option.
Although a strong Windows 7 password is said to be the best way to protect your computer data from unauthorized access, it also means trouble if you forgot Windows 7 password without a password reset disk or an administrator account, to some extent. If you want to bypass Windows 7 password on that condition, I’m afraid that the only you have to resort to a third-party tool like Ophcrack on the presupposition that you cannot recall it any longer.
Before following the below steps, you should learn about what Ophcrack is.
Ophcrack is a free open source (GPL licensed) program that cracks Windows passwords by using LM hashes through rainbow table. Coming with a Graphical User Interface and running on multiple platforms, it allows you to retrieve the forgotten Windows 7password without any knowledge of any existing passwords.
Follow the steps listed below to perform Windows 7 password crack with Ophcrack.
1. Load the Ophcrack CD to the computer, install and run it.
2. Click on Load and select the appropriate password LM (LAN Manager) hash to use or choose PWDUMP File if the hash was dumped and saved using pwdump2.
3. Otherwise choose encrypted SAM to allow Ophcrack to dump the hashes from the SAM and SYSTEM files retrieved from a Windows machine while booting on another disk.
4. Click Tables, and select the location or folder to store the rainbow hash tables downloaded or installed by the installer.
5. Select the type of tables you wish to use.
6. Click Launch to start the cracking process.
Alternative option: Use Windows 7 password reset tool
Although the Ophcrack is free, its 496MB LiveCD ISO image will take you much time for download. What’s worse, it cannot crack Windows 7 passwords greater than 14 characters. Why not try a Windows 7 password reset tool like Windows Password Buster? It can guarantee 100% recovery rate, regardless of the lost password length and complexity.
Unlike Ophcrack, Windows Password Buster actually allows to unlock Windows 7 password to blank by burning a bootable password reset CD/DVD/USB flash drive. And the whole process will cost you no more than 5 minutes. No data loss or damage.
