如何破解您忘记的Windows密码

Here at How-To Geek, we’ve covered many different ways to reset your password for Windows—but what if you can’t reset your password? Or what if you’re using drive encryption that would wipe out your files if you changed the password? It’s time to crack the password instead.

在How-To Geek上，我们介绍了许多用于Windows重置密码的方法，但是如果您无法重置密码怎么办？或者，如果您使用的驱动器加密会在更改密码后清除文件，该怎么办？现在该破解密码了。

To accomplish this, we’ll use a tool called Ophcrack that can crack your password so you can login without having to change it.

为此，我们将使用一个名为Ophcrack的工具，该工具可以破解您的密码，以便您无需更改即可登录。

下载Ophcrack (Download Ophcrack)

The first thing we will need to do is download the CD image from Ophcrack’s website. There are two options to download, XP or Vista, so make sure you grab the right one. The Vista download works with Windows Vista or Windows 7, and the only difference between XP and Vista is the “tables” Ophcrack uses to determine the password.

我们需要做的第一件事是从Ophcrack的网站下载CD映像。 XP或Vista有两种下载选项，因此请确保您选择了正确的选项。 Vista下载适用于Windows Vista或Windows 7，XP和Vista之间的唯一区别是Ophcrack用于确定密码的“表”。

Once the .iso file is downloaded, burn it to a CD using the guide below.

下载.iso文件后，请使用以下指南将其刻录到CD。

If you are going to be cracking your password on something that doesn’t have a CD drive, such as a netbook, download the universal USB creator from PenDrive Linux (Link Below). A USB drive will not only run faster but you can also use a single USB drive for Windows XP, Vista, and 7 if you copy the needed tables to the drive.

如果要在没有CD驱动器的东西(例如上网本)上破解密码，请从PenDrive Linux下载通用USB创建器(下面的链接)。 USB驱动器不仅运行速度更快，而且如果将所需的表复制到Windows XP，Vista和7，也可以使用单个USB驱动器。

To create a USB drive that works with all versions of Windows, download the free password tables from Ophcrack’s website.

要创建适用于所有Windows版本的USB驱动器，请从Ophcrack的网站下载免费的密码表。

Note: There are free tables available on Ophcrack’s website and there are paid tables, the paid tables will typically get the job done faster and will be able to crack more complex passwords but the paid tables may not fit on a USB drive because they range in size from 3 GB to 135 GB.

注意：Ophcrack网站上有免费的表，有付费表，付费表通常可以更快地完成工作，并且能够破解更复杂的密码，但是付费表可能不适合USB驱动器，因为它们的范围在大小从3 GB到135 GB。

Now extract the tables to \tables\vista_free on the USB drive and they will be used automatically by Ophcrack.

现在将表提取到USB驱动器上的\ tables \ vista_free中，Ophcrack将自动使用它们。

从CD / USB引导 (Boot from CD/USB)

Boot the computer from the CD or USB drive that you created.

从您创建的CD或USB驱动器引导计算机。

Note: On some computers you may have to go into the BIOS settings to change the boot order or push a key to show the boot menu.

注意：在某些计算机上，您可能必须进入BIOS设置才能更改启动顺序或按某个键以显示启动菜单。

Once the disk is done booting, Ophcrack should start automatically and will begin cracking the passwords for all of the users on your computer.

一旦磁盘完成启动，Ophcrack应该会自动启动，并将开始为您计算机上的所有用户破解密码。

Note: If the computer boots and you only have a blank screen or Ophcrack doesn’t start, try restarting the computer and selecting manual or low RAM options on the live CD boot menu.

注意：如果计算机启动，并且只有空白屏幕或Ophcrack无法启动，请尝试重新启动计算机并在实时CD启动菜单上选择手动或低RAM选项。

If you have a complex password it will take a lot longer than simple passwords, and with the free tables your password may never be cracked. Once the crack is done you will see the password in plain text, write it down and reboot the machine to login. If your password isn’t cracked, you can also log in as one of the other users with admin rights and then change your password from within Windows.

如果您有一个复杂的密码，它将比简单的密码花费更多的时间，并且使用免费表，您的密码可能永远不会被破解。破解完成后，您将看到纯文本密码，将其写下来并重新启动计算机以登录。如果您的密码没有被破解，您还可以以具有管理员权限的其他用户之一身份登录，然后在Windows中更改密码。

With the free tables available you will not be able to crack every password, but the paid tables range from $100 to $1000 so you may be better off just resetting your password with on of these tutorials:

有了可用的免费表，您将无法破解每个密码，但是付费表的价格从100美元到1000美元不等，因此，最好使用以下教程中的重置密码，这样更好：

Change password with Linux System Rescue CD

If you aren’t using drive encryption and you’ve got a tough password, it’s usually much faster to reset the password using one of the tools above, but we like to show you all the different techniques that you can use.

如果您不使用驱动器加密，并且密码比较复杂，那么使用上述工具之一重置密码通常会更快，但是我们希望向您展示所有可以使用的不同技术。
