Here are top 3 methods to help you fix the “This app has been blocked for your protection” in Windows 10.

How To Fix “This app has been blocked for your protection” in Windows 10

Method 1. Using elevated Command Prompt

To bypass the error “This app has been blocked for your protection“, you can run the application from an elevated Command Prompt. To do that, follow these steps below:

Step 1. Click Start menu and put “cmd“. Then right-click on Command Prompt in the search results and click on Run as administrator.

Step 2. Locate the app’s setup file and then right-click on it and click Properties. Copy and paste its location into Command Prompt and type the exact file name.

In my example, it would be C:\Users\Windows10freeapps\Downloads\FoxitReader93_enu_Setup_Clean.exe

Press Enter.

Step 3. When finished, you can close command prompt window.

Method 2. Disable Windows SmartScreen

Windows SmartScreen will block suspicious or unrecognized apps from running on your PC. If you are sure the files are safe, you could turn off Windows Defender SmartScreen. To do that, follow these steps below:

Step 1. Go from Start menu, click Settings.

Step 2. Select on Privacy.

Step 3. In General tab, under Turn on SmartScreen Filter to check web content(URLs) that Windows Store apps use, you can turn that switch on or off.

Method 3. Using Local Group Policy Editor

You can fix the error “This app has been blocked for your protection” by changing corresponding policy. To do so, follow these steps below:

Step 1. Press Windows Key + R then put gpedit.msc in run dialog box. Hit Enter to open Local Group Policy Editor. You can refer how to fix “Windows cannot find gpedit.msc” in Windows 10 from this tutorial.
