有时，我们可能需要对数据进行加密并保持安全和私密，以便对其他人隐藏，在这种情况下，我们必须对数据进行安全加密。Windows可让您轻松加密文件夹数据，默认情况下启用此功能。因此，如果您需要加密文件夹内的数据，只需右键单击该文件夹，选择Properties。然后在“属性^(Properties)”窗口中，单击“高级^(Advanced)” ；在“高级属性^{(Advanced Attribute)}”窗口中，有加密数据的选项。只需选中此选项即可随时随地加密数据。

加密内容以保护数据选项被禁用或灰显

但是，如果您可以选择加密数据，例如。加密内容以保护数据^{( Encrypt contents to secure data)}选项已禁用？好吧，这就是我们最近在运行Windows 8的系统上遇到的问题。我们尝试检查不同文件夹的此问题并得到相同的结果。如果您也遇到此问题，请尝试以下步骤来修复您的系统。此修复适用于所有Windows Vista及更高版本。

无法在Windows 11/10加密^(Encrypt)文件夹数据

1.按Windows Key + R组合，在运行^(Run) 对话框中键入 put regedit ，然后^(regedit)按 Enter^(Enter)打开注册表编辑器。^{( Registry Editor.)}

2.在注册表编辑器^{(Registry Editor)}的左窗格中，导航到：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

3.在上面显示的窗口的右窗格中，查找名为注册表DWORD ( REG_DWORD ) 的^(REG_DWORD)NtfsDisableEncryption，因为您遇到了这个问题，您会发现这个DWORD的值数据^{(Value data)}设置为1。双击相同的DWORD进行修改：

4.在上面显示的窗口中，将数值数据^{(Value data)}更改为0。单击确定^(OK)。您现在可以关闭注册表编辑器^{(Registry Editor)}并重新启动以进行修复。

希望这对您有所帮助。

注意^(NOTE)：这似乎只适用于专业版^(Pro)和企业^(Enterprise)版。
