Windows Vista includes a file encryption technology very similar from a user perspective to the one that existed in Windows XP, but Vista makes it very easy to make a backup of the file encryption key. In XP, your encrypted files would be lost if you changed your password. In Vista, an encryption key is used to sign the encrypted files, which also means it can be backed up.

从用户的角度来看，Windows Vista包含一种文件加密技术，与Windows XP中存在的技术非常相似，但是Vista使得备份文件加密密钥非常容易。 在XP中，如果更改密码，加密的文件将丢失。 在Vista中，使用加密密钥对加密的文件进行签名，这也意味着可以对其进行备份。

It’s critically important that you make a backup of your encryption key if you decide to use the encryption features. Thankfully Vista reminds you immediately after the first time you encrypt a file.

如果决定使用加密功能，则备份加密密钥至关重要。 幸运的是，Vista会在您第一次加密文件后立即提醒您。

To use the Wizard to back up the encryption key, just click on the popup notification when it comes up.

要使用向导备份加密密钥，只需在弹出通知出现时单击它。

Select “Back up now” from the wizard screen.

从向导屏幕中选择“立即备份”。

Hit next…

下一个…

You may as well select all the possible information to back up, in case you have multiple keys for some reason.

如果出于某种原因有多个键，则最好选择所有可能的信息进行备份。

You’ll have to enter a password for the key. This password will be used if you try and restore the encryption key later. Make sure you choose a good password, and make sure that it’s also something you’ll remember. This is where a password safe application might help.

您必须输入密钥的密码。 如果您稍后尝试恢复加密密钥，将使用此密码。 确保您选择了正确的密码，并且还记得该密码。 这是密码安全应用程序可能会提供帮助的地方。

On the next screen, you can enter a filename, or you can click the Browse button and choose a folder location. (It was easier for me to click Browse) Type in the file name that you want here.

在下一个屏幕上，您可以输入文件名，也可以单击“浏览”按钮并选择文件夹位置。 (对我来说，单击浏览比较容易)在此处键入所需的文件名。

Hit next and then finish, and you should see that the export was succesful.

单击“下一步”，然后完成操作，您应该看到导出成功。

Now it’s very important to back that file up to somewhere safe. A spare USB drive wouldn’t be a bad idea.

现在将文件备份到安全的位置非常重要。 备用USB驱动器不是一个坏主意。

Note: If you selected “Never Back Up”, or you just don’t see the popup notification, don’t fear, you can still back up the encryption key. Just open up Control Panel, and type in “certificate” (or the first few letters, as you can see below) 

注意：如果选择“从不备份”，或者只是看不到弹出通知，请放心，您仍然可以备份加密密钥。 只需打开控制面板，然后输入“ certificate”(证书)(或前几个字母，如下所示)

Click on “Manage file encryption certificates” and then hit next on the resulting dialog window.

单击“管理文件加密证书”，然后在出现的对话框窗口中单击下一步。

You should see a very simple screen that makes it easy to back up the encryption key in a single step. Honestly, I think this route is faster than using the other wizard, and it bugs me that they made two different screens to accomplish the same thing. 

您应该看到一个非常简单的屏幕，使您可以轻松地一步备份加密密钥。 坦率地说，我认为这条路线比使用其他向导要快，这让我很困惑，他们制作了两个不同的屏幕来完成同一件事。

Same as before, select a filename and password (Use the browse button to select the filename more easily)

与以前一样，选择文件名和密码(使用浏览按钮更轻松地选择文件名)

Check the box for “I’ll update my encrypted files later”, because you aren’t actually changing the certificate at this point, just backing it up.

选中“我稍后再更新我的加密文件”复选框，因为此时您实际上并没有更改证书，只需备份它即可。

…make sure that you back up the key file safely.

…确保安全备份密钥文件。
