Release Notes

Sandboxie-Plus 1.16.4 / Classic 5.71.4 has been released on October 2nd, 2025. This version introduces a new protection option that blocks non-administrative instances of the session leader, such as Sandman.exe or Sbiectrl.exe, from accessing encrypted box data. This safeguard is enabled by default, though it can be disabled by setting ProtectAdminOnly=n if required. In addition to this enhancement, the release resolves a critical issue where Sandboxie-Plus 1.16.3 failed to connect to the driver on Windows Preview Build 27943, as tracked in issue #5003. Stability has also been improved with a fix for crashes related to the latest Signal client. Furthermore, the internal checks in Thread_CheckObject_CommonEx have been strengthened to provide more robust handling of encrypted boxes. This update continues the project’s focus on reliability, compatibility with evolving Windows builds, and stronger data protection.
