Add Unblock File Context Menu in Windows 10

When you download files from the Internet, Windows adds zone information to it and stores it in the file's NTFS alternate steam. Windows 10 shows you a security warning every time you try to open it. Some file types are fully blocked from opening. SmartScreen, a security feature of Windows 10, causes this behavior. But even if SmartScreen is turned off, you still get a warning and need to unblock downloaded files. To save your time, you can add a special context menu to unblock files faster.


When you try to open a file which was downloaded from the Internet, you see a warning like this:Windows 10 SmartScreen Warning

To avoid it and unblock a single file, you can use either the File Properties or PowerShell. To unblock all files in a folder in Windows 10, you need to use PowerShell.

To save your time, you can add a special context menu entries, so you will be able to unblock the selected file or all files in a folder. See the following screenshots:
