App control for business on Windows involves managing which software is trusted and allowed to run, often through mechanisms like Windows Managed Installer and driver signing policies. Recent discussions highlight a June 2026 Patch Tuesday update addressing CVE-2026-45604, an information disclosure vulnerability in the Windows Application Identity subsystem that could affect enterprise app control decisions. Additionally, Microsoft is shifting kernel-mode driver trust from legacy cross-signing to Windows Hardware Compatibility Program validation starting April 2026, impacting legacy hardware and custom drivers. These changes aim to harden security but require testing for compatibility in business environments.
