弹出EFS加密密钥
我收到通知，要求在 Vista 中备份 EFS 的加密密钥，但我尚未启用位锁或驱动器加密。
有人知道如何找出哪些文件可能被加密，或者解释为什么它会通知我？
I'm getting notifications to back up my encryption key for EFS in Vista, however i haven't enabled bit locker or drive encryption.
Anyone know how to find out what files may be encrypted or have an explanation for why it would notify me?

Clippy 注意到您的文件中有敏感信息并自动对其进行加密。
你确定是EFS的？ 以前曾有过一些事情提示我备份我的密钥，但我并不确切知道它们的用途。 我以为它就像受 DRM 保护的文件或其他东西。 因为是不久前的事了，所以具体细节我不太记得了。 我从来没有备份过它，也没有被任何事情锁定。
Clippy noticed that you have sensitive information in your files and automatically encrypted them.
Are you sure it's for EFS? I've had things prompt me to backup my keys before, but I didn't know exactly what they were to. I was assuming it was like a DRM protected file or something. It was a while ago so i don't remember exactly what the specific details were. I never backed it up and haven't been locked out of anything.
解压缩 DroidDraw (http://www.droiddraw.org/) 后，我收到了同样的消息。
这是一个普通的（我认为）zip 文件。 右键点击它，全部解压。 生成的文件夹/文件已加密。 Win 立即提示我备份 EFS 密钥。
Win Vista 和 Win 7 上的行为相同。
I've got the same message after un-zipping DroidDraw (http://www.droiddraw.org/).
It's a normal (I think) zip file. Right click on it, extrat all. The resulting folder/files were encrypted. Immediatelly Win prompted me to backup EFS keys.
Same behaviour on Win Vista and Win 7.
要找出系统上的哪些文件已使用 EFS 加密，您只需运行以下命令：
To find out which files on your system have been encrypted with EFS, you can simply run this command:
是的，它是 EFS：

为什么要备份证书和密钥？
Yes it's EFS:

Why should I backup the certificate and key?
EFS 加密通常通过“文件属性”对话框的“高级”选项卡实现，最好在文件夹级别进行。
但在 Vista 上，我记得在我的新计算机上看到过这条消息，绝对没有加密过单个文件。 因此，我同意在第一次使用 EFS 之前要求您备份密钥会令人困惑。 Windows-7 从来没有问过我，所以可能这就是它未来的工作方式。
EFS encryption is typically achieved via the "Advanced" tab of the "File Properties" dialog and it's best to do it at the folder-level.
But on Vista I remember seeing this message on my new computer, definitely never having encrypted a single file. So I AGREE it's confusing to ask you to back up the key, until the FIRST USE of EFS. Windows-7 has never asked me, so probably that's the way it works in the future.
在使用 Windows 7 几个月后，我第一次收到同样的消息。 如上所述运行 cipher.exe 显示我下载的字体文件（Anonymous Pro）已设置加密属性（右键单击文件，属性，常规选项卡，单击高级）。 它还具有授予未知帐户读取和执行权限的安全设置。 (!) 我不知道为什么字体文件会设置加密标志。
如果您突然收到此消息，可能是对您刚刚下载的某些内容的响应。
I just got this same message for the first time after using Windows 7 for many months. Running cipher.exe as noted above revealed that a font file I downloaded (Anonymous Pro) had the encryption attribute set (right-click the file, properties, General Tab, click Advanced). It also had security settings granting an unknown account read and execute permissions. (!) I don't know why a font file would have the encryption flag set.
If you just got this message out of the blue, perhaps it is in response to something you just downloaded.
