What is SmartSceen?

SmartScreen is a cloud-based security tool built into Windows 8 and Windows 10. Basically, it reaches Microsoft's servers every time you install an app. This way, it will help you confirm whether the software you intend to install is safe and whether or not it has malware or viruses.

This is a layer of protection that Microsoft provides to users. Even with antivirus software installed, SmartScreen still provides you with the latest information about threats when it connects to Microsoft servers each time it scans.

However, if SmartScreen encounters a Microsoft connection error, it will display the message >SmartScreen can't be reached right now . It also tells you the publisher and name of the application. Thanks to that, you can make a more informed decision before choosing Run or Don't run . Below are some steps to fix SmartScreen not working error on Windows.

Because SmartScreen relies on Microsoft's servers to check the safety status of certain apps, you must be online for it to work. The easiest way to test your network speed is to use Speedtest.net. If you see inconsistent download or upload speeds or 0Mbps, the error may be due to the service provider.

In this case, first, you should reset the modem and router. If using a wired network, try disconnecting and reconnecting the LAN cable. Finally, run Windows Network Troubleshooter if the above steps don't work.

Check SmartScreen status

The reason SmartScreen does not work can sometimes be due to someone else or some factor disabling it. You can easily check the SmartScreen status in Windows Security Center as follows: open the Start menu > click the Settings logo (jagged icon).
