How to Disable the Windows 10 ‘SmartScreen’ Filter for Apps and Files

The Intrusive Security Wall

Windows 10 includes a built-in security feature called “SmartScreen.” Whenever you attempt to run a newly downloaded executable file (.exe), SmartScreen intercepts the launch, contacts Microsoft’s servers, and checks the file’s digital signature against a database of known threats. If the file is unrecognized or uncommonly downloaded, it blocks the launch and displays a massive blue warning screen stating: “Windows protected your PC.”

While SmartScreen is an excellent safety net for novice users, it is incredibly annoying for software developers, IT professionals, or power users who frequently download and test obscure, unsigned, or open-source software tools. If you know exactly what you are downloading and use a dedicated antivirus program, you can disable SmartScreen to stop these intrusive blue warning screens.

How to Disable the SmartScreen Filter

You can turn off SmartScreen for apps and files inside the Windows Security app.

1. Click the Start button, type Windows Security, and press Enter to open the app.
2. In the left-hand sidebar, click on App & browser control.
3. Click the blue link that says Reputation-based protection settings.
4. You will see several toggle switches on this page. Locate the toggle switch labelled “Check apps and files” (This specifically controls the SmartScreen filter for unrecognized apps downloaded from the web).
5. Toggle the switch to the Off position.
6. Windows User Account Control (UAC) may prompt you to confirm the change. Click Yes.
7. You can also toggle off “SmartScreen for Microsoft Edge” if you don’t want it blocking downloads within the Edge browser.

With this feature disabled, you can now download and execute obscure software, beta tools, and custom scripts instantly, without Windows interrupting your workflow with a blue warning screen.
