Microsoft announced the public preview launch of Win32 app isolation, a new Windows 11 security feature designed to sandbox 32-bit desktop applications.
Recently announced during Microsoft's Build 2023 conference, Win32 app isolation uses AppContainerto boost security by mitigating the potential harm caused by compromised applications and protecting the user's privacy.
It also ensures that apps are running with low privilege and implements the principle of least privilege to prevent unauthorized access to the user's information without first asking for consent.
"The Win32 application is launched as a low integrity process using AppContainer, which is recognized as a security boundary by Microsoft," said David Weston, Microsoft VP for Enterprise & OS Security.
"Consequently, the process is limited to a specific set of Windows APIs by default and is unable to inject code into any process operating at a higher integrity level."
