Windows has blocked access to this file; Unblock a File in Windows 10

At times, you may download a file from the Internet or receive one by email. Windows classifies certain files as unsafe downloads and attachments by identifying the files type and the security settings for each file. For doing this, it uses the Attachment Manager in Windows, which is a service that gets activated whenever you receive an e-mail message with an attachment and from unsafe files that you might save from the Internet.

The Attachment Manager classifies such files as High Risk, Moderate Risk, and Low Risk. If the file you are trying to access or open or extract belongs to the High-Risk type, Windows 10/8 will block the file from being opened. You can read more about how Windows OS treats each file.

I recently received a zipped .exe file by mail from a trusted source. I downloaded the file to my Windows desktop but was unable to extract the contents. I received a warning box with the following message:

Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file.

The only option is to click on OK and find that you are left with an empty folder in hand! So how do you extract such contents, knowing very well that the file is from a trusted source in therefore safe.

Unblock a File in Windows 10

To open such files or extract contents of such blocked zipped files, right-click on the file and open Properties.

You may see a message – This file came from another computer and might be blocked to help protect this computer. Click on the Unblock button and then on Apply/OK.

You will now be able to access or open the downloaded file.

You can also use this method to whitelist or allow apps your trust.

TIP: This post shows how to bulk Unblock multiple files downloaded from the Internet.

Unblock button appears again

When you click the Unblock button, it removes the Zone Identifier information. But at times, this does not happen for some reason and the Unblock button may appear again in the Properties box.

Create a system restore point first.

You may then download Streams from Microsoft SysInternals and run the following command as an administrator:

This guide describes how to run the System File Checker tool (SFC.exe) to scan your system files and to repair missing or corrupted system files (including .DLL files). If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.

To run DISM scan you need to open Command Prompt as administrator again and to type in this command: «DISM /Online /Cleanup-Image /RestoreHealth». Press Enter on your keyboard to execute it.

Reinstall Graphics Drivers

A device driver is software that informs the operating system and other software how to interact with particular hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or people. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly, if at all. You might want to try to uninstall and then reinstall the graphic drivers. To do this, open Device Manager by right-clicking the Start button and selecting «Device Manager» result from the contextual menu.

In Device Manager, find «Display adapters», expand it, right-click your graphics device and select «Uninstall» from the drop-down menu to uninstall it.

In the popped-up window, click «Uninstall». Make sure that you check the «Delete the driver software for this device.» checkbox. Restart your computer. Windows will automatically install the missing graphics drivers the next time you start your Windows. Check if this fixes the «Application has been blocked from accessing Graphics hardware» error.

If for some reason Windows could not or won’t install the missing graphics drivers, then go to Device Manager again and right-click your computer name, select «Scan for hardware changes». It should detect missing drivers and install them.

Update Graphics Drivers

Another way to fix the «Application has been blocked from accessing Graphics hardware» error is to update your graphics drivers manually or automatically. To do so open Device Manager by right-clicking the Start button and selecting «Device Manager» result from the contextual menu again. In Device Manager, find «Display adapters», expand it, right-click your graphics device and select «Update driver» from the contextual menu.

You will be asked if you want to search for updated driver software automatically or to browse your computer for driver software. If you select the first option, then Windows will search your computer and the Internet for the latest driver software for your device.

Follow the instructions and update your graphics drivers. Restart your computer and see if this fixed the «Application has been blocked from accessing Graphics hardware» error.
