The built-in security tools in Windows vary between versions 10 and 11, with the latter offering enhanced capabilities from Microsoft to guard against digital and physical risks. While the core suite remains consistent, Windows 11 includes specialized options that often go unnoticed amid frequent updates to underlying safeguards. To boost adoption, Microsoft is promoting a distinctive Windows 11 tool known as Smart App Control.
This feature evaluates applications by scanning them through Microsoft's cloud-based security platform to assess their reliability. It applies to every type of software, including those downloaded directly or obtained from the Microsoft Store. Serving as an extension to the standard antivirus, firewall, and related defenses in Windows Security, it adds protection against tampered files and malicious software.
Beginning in January 2025, Windows 11 systems may initiate Smart App Control in a monitoring phase that observes user behavior over 30 days to determine suitability. This approach accounts for potential issues with certain developer tools or gaming software that could clash with the control. Upon successful evaluation, the system will enable the full functionality without further input.
However, existing setups might lack this evaluation phase if installed prior to its deployment on new or reset devices. Users should access Windows Security to review their configuration. Following a Microsoft update on February 10, 2026, the option to enable this protection extends to all Windows 11 computers, beyond initial setups.
Navigate to the App & browser control section and ensure the Evaluation mode is active. Confident that no essential programs will be affected? Opt to activate the complete mode directly.
Initially, Microsoft restricted Smart App Control to fresh installations to guarantee a secure starting point for the verification process. The recent adjustment eliminates this limitation, simplifying access for everyone amid rising threats like fraud, deceptive emails, viruses, and cyber intrusions. Handling credentials, protective software, and patches already poses significant challenges.
