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，我們介紹了許多用于Windows重置密碼的方法，但是如果您無法重置密碼怎么辦？ 或者，如果您使用的驅動器加密會在更改密碼后清除文件，該怎么辦？ 現在該破解密碼了。

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

為此，我們將使用一個名為Ophcrack的工具，該工具可以破解您的密碼，以便您無需更改即可登錄。

下載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.

我們需要做的第一件事是從Ophcrack的網站下載CD映像。 XP或Vista有兩種下載選項，因此請確保您選擇了正確的選項。 Vista下載適用于Windows Vista或Windows 7，XP和Vista之間的唯一區別是Ophcrack用于確定密碼的“表”。

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

下載.iso文件后，請使用以下指南將其刻錄到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.

如果要在沒有CD驅動器的東西(例如上網本)上破解密碼，請從PenDrive Linux下載通用USB創建器(下面的鏈接)。 USB驅動器不僅運行速度更快，而且如果將所需的表復制到Windows XP，Vista和7，也可以使用單個USB驅動器。

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

要創建適用于所有Windows版本的USB驅動器，請從Ophcrack的網站下載免費的密碼表。

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網站上有免費的表，有付費表，付費表通常可以更快地完成工作，并且能夠破解更復雜的密碼，但是付費表可能不適合USB驅動器，因為它們的范圍在大小從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.

現在將表提取到USB驅動器上的\ tables \ vista_free中，Ophcrack將自動使用它們。

從CD / USB引導 (Boot from CD/USB)

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

從您創建的CD或USB驅動器引導計算機。

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：在某些計算機上，您可能必須進入BIOS設置才能更改啟動順序或按某個鍵以顯示啟動菜單。

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

一旦磁盤完成啟動，Ophcrack應該會自動啟動，并將開始為您計算機上的所有用戶破解密碼。

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：如果計算機啟動，并且只有空白屏幕或Ophcrack無法啟動，請嘗試重新啟動計算機并在實時CD啟動菜單上選擇手動或低RAM選項。

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.

如果您有一個復雜的密碼，它將比簡單的密碼花費更多的時間，并且使用免費表，您的密碼可能永遠不會被破解。 破解完成后，您將看到純文本密碼，將其寫下來并重新啟動計算機以登錄。 如果您的密碼沒有被破解，您還可以以具有管理員權限的其他用戶之一身份登錄，然后在Windows中更改密碼。

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:

有了可用的免費表，您將無法破解每個密碼，但是付費表的價格從100美元到1000美元不等，因此，最好使用以下教程中的重置密碼，這樣更好：

• Reset password with Ubuntu live CD

  使用Ubuntu Live CD重設密碼

• 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.

如果您不使用驅動器加密，并且密碼比較復雜，那么使用上述工具之一重置密碼通常會更快，但是我們希望向您展示所有可以使用的不同技術。
