Updated May 27, 2025
Microsoft is positioning its Smart App Control (SAC) as a premier PC antivirus solution for Windows 11 users. the company claims this AI-driven feature offers a novel approach to security, proactively blocking suspicious applications before they can compromise a system. However, security experts urge caution, suggesting SAC should complement, not replace, traditional antivirus software.
SAC, introduced in recent Windows 11 updates, requires a clean operating system installation to function optimally. Microsoft says that users who enable the feature will experience enhanced security. Unlike traditional antivirus programs that react to detected threats, Smart App Control employs artificial intelligence to predict and prevent malicious software from running.

Microsoft asserts that Smart App Control uses AI to determine the safety of applications on Windows 11. The company also claims that SAC has a lighter impact on system performance compared to traditional antivirus programs that continuously scan files.
Smart app Control harnesses the power of AI to help predict which apps are safe to run on Windows 11.
While microsoft markets SAC as a groundbreaking innovation, some experts note that the underlying concept is similar to security practices employed on older Windows systems. They also caution against relying solely on Microsoft for security, recommending autonomous testing platforms to find reliable antimalware solutions.
Concerns have also been raised about potential performance slowdowns caused by SAC due to bugs or compatibility issues. Broadcom, for example, has reported issues related to SAC impacting performance.
What’s next
Users are advised to remain vigilant and consider a multi-layered security approach, combining Smart App Control with established antivirus solutions for comprehensive protection against evolving cyber threats. Independent testing and reviews can help users choose the most effective tools for their needs.
