修复下载的文件在 Windows 10 中被阻止： ^{(Fix Downloaded Files from being Blocked in Windows 10: )}当您尝试打开或执行刚刚通过 Internet 下载的文件时，您可能会收到一条安全警告，指出“无法验证发布者并且该文件可能存在安全威胁^{(The publisher could not be verified and the file might be a security threat)}”。当Windows无法验证文件的数字签名时会发生这种情况，因此会出现错误消息^{(error message)}。Windows 10 附带一个附件管理器^{(Attachment Manager)}，它可以识别附件是安全的还是不安全的，如果文件不安全，它会在您打开文件之前向您发出警告。

Windows 附件管理器^{(Windows Attachment Manager)}使用IAttachmentExecute 应用程序^{(IAttachmentExecute application)}编程接口 ( API ) 来查找文件类型和文件关联^{(file type and file association)}。当您从Internet下载一些文件并将其保存在您的磁盘 ( NTFS )上时， Windows会将特定的元数据添加到这些下载的文件中。这些元数据保存为备用数据流^{(Alternate Data Stream)}( ADS )。当Windows将元数据作为附件添加到下载文件^{(download file)}时，它被称为区域信息^{(Zone Information)}。此区域信息^{(zone information)}不可见，并添加到下载文件^{(download file)}作为备用数据流^{(Alternate Data Stream)}( ADS )。

当您尝试打开下载的文件时，Windows 文件资源管理器^{(Windows File Explorer)}还会检查区域信息^{(zone information)}并查看文件是否来自未知来源。一旦 Windows 识别出该文件无法识别或来自未知来源，Windows 智能屏幕^{(Windows Smart Screen)}警告将显示“ Windows 智能屏幕阻止无法识别的应用程序启动。运行此应用程序可能会使您的 PC 面临风险^{(Windows smart screen prevented an unrecognized app from starting. Running this app might put your PC at risk)}“。

如果您希望取消阻止该文件，则可以通过右键单击下载的文件然后选择Properties来手动执行此操作。在属性窗口选中“取消^{(checkmark “)}阻止”，然后单击“应用^(Apply)”，然后单击“确定”。但是用户不喜欢这种方法，因为每次下载文件时都这样做很烦人，而是可以禁用附加区域信息^{(zone information)}，这意味着不会有任何智能屏幕安全警告^{(screen security warning)}。因此，不要浪费任何时间，让我们^{(time let)}看看如何在下面列出的教程的帮助下修复下载的文件^{(Fix Downloaded Files)}在Windows 10中被阻止。^{(Windows 10)}

Fix Downloaded Files from being Blocked in Windows 10

Fix Downloaded Files from being Blocked in Windows 10: When you try to open or execute the files you just download over the internet you may receive a security warning stating “The publisher could not be verified and the file might be a security threat“. This happens when Windows can’t verify the digital signature of the file, hence the error message. Windows 10 comes with an Attachment Manager which identifies an attachment either safe or unsafe, if the file is unsafe then it warns you before you open the files.

Windows Attachment Manager uses the IAttachmentExecute application programming interface (API) to find the file type and file association. When you download some files from the Internet and save it on your disk (NTFS) then Windows add specific metadata to these downloaded files. These metadata are saved as an Alternate Data Stream (ADS). When Windows adds metadata to the download files as an attachment then it is known as Zone Information. This zone information is not visible and is added to the download file as an Alternate Data Stream (ADS).

When you try to open the downloaded file then Windows File Explorer also checks the zone information and see if the file came from an unknown source. Once Windows recognizes that the file is an unrecognized or came from unknown sources the Windows Smart Screen warning will appear stating “Windows smart screen prevented an unrecognized app from starting. Running this app might put your PC at risk“.

If you wish to unblock the file then you could do that manually by right-clicking on the downloaded file and then select Properties. Under properties window checkmark “Unblock” then click Apply followed by OK. But users don’t prefer this method as it’s very annoying to do that every time you download a file instead you could disable the additional zone information which means there won’t be any smart screen security warning. So without wasting any time let’s see How to Fix Downloaded Files from being Blocked in Windows 10 with the help of the below-listed tutorial.
