Smart App Control prevents users from running malicious applications by blocking untrusted or unsigned applications. Smart App Control goes beyond previous built-in browser protections by adding another layer of security that is woven directly into the core of the OS at the process level. Using AI, Smart App Control only allows processes to run if they're predicted to be safe based on existing and new intelligence updated daily.

Smart App Control builds on top of the same cloud-based AI used in App Control for Business to predict the safety of an application so that users can be confident that their applications are safe and reliable on their new Windows devices. Additionally, Smart App Control blocks unknown script files and macros from the web, greatly improving security for everyday users. Smart App Control shipped in evaluation mode for new device starting in Windows 11, version 22H2.

Additionally, Smart App Control blocks unknown script files and macros from the web, greatly improving security for everyday users.
We've been making significant improvements to Smart App Control to increase the security, usability, and cloud intelligence response for apps in the Windows ecosystem. Users can get the latest and best experience with Smart App Control by keeping their PC up to date via Windows Update every month. We've been making significant improvements to Smart App Control to increase the security, usability, and cloud intelligence response for apps in the Windows ecosystem. Users can get the latest and best experience with Smart App Control by keeping their devices up to date via Windows Update every month.
Additionally, evaluation mode starts automatically enabling devices that the cloud AI model predicts will have a good experience with Smart App Control in the coming months, first starting with users in North America and eventually expanding to other regions. To ensure that users have a seamless experience with Smart App Control enabled, we ask developers to sign their applications with a code signing certificate from the Microsoft Trusted Root Program. Developers should include all binaries, such as exe, dll, temp installer files, and uninstallers. Trusted signing makes the process of obtaining, maintaining, and signing with a trusted certificate simple and secure.
As a developer, to ensure that your users have a seamless experience with Smart App Control enabled, we ask that you sign your application with a code signing certificate from the Microsoft Trusted Root Program. Make sure to include all binaries, such as exe, dll, temp installer files, and uninstallers. Trusted signing makes the process of obtaining, maintaining, and signing with a trusted certificate simple and secure. More on that later in this doc. Smart App Control is disabled on devices enrolled in enterprise management. We suggest enterprises running line-of-business applications continue to use *App Control for Business*.
Devices running previous versions of Windows 11 must be reset with a clean installation of the operating system to take advantage of this feature.

Your organization is only as secure as the applications that run on your devices. With *application control*, apps must earn trust to run, in contrast to an application trust model where all code is assumed trustworthy. By helping prevent unwanted or malicious code from running, application control is an important part of an effective security strategy. Many organizations cite application control as one of the most effective means of defending against executable file-based malware.

App Control for Business (previously called *Windows Defender Application Control*) and AppLocker are both included in Windows. App Control for Business is the next-generation app control solution for Windows and provides powerful control over what runs in your environment. Customers who were using AppLocker on previous versions of Windows can continue to use the feature as they consider whether to switch to App Control for Business for stronger protection.

## Microsoft vulnerable driver blocklist ## Microsoft vulnerable driver blocklist
The Windows kernel is the most privileged software and is therefore a compelling target for malware authors. Since Windows has strict requirements for code running in the kernel, cybercriminals commonly exploit vulnerabilities in kernel drivers to get access. Microsoft works with ecosystem partners to constantly identify and respond to potentially vulnerable kernel drivers. Prior to the Windows 11 2022 Update, Windows enforced a block policy when hypervisor-protected code integrity (HVCI) was enabled to prevent vulnerable versions of drivers from running. Beginning with the Windows 11 2022 Update, the block policy is now on by default for all new Windows PCs, and users can opt in to enforce the policy from the Windows Security app. The Windows kernel is the most privileged software and is therefore a compelling target for malware authors.
