Release v1.16.4 / 5.71.4 Latest
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.

Thanks for sharing the latest Sandboxie-Plus release, bjm_! The new protection feature for encrypted boxes sounds like a solid addition to security. Good to see the compatibility fixes for Windows Insider builds and the stability improvements too.

If anyone runs into issues during the update, remember the tip: uninstall the old version (keep your sandboxie.ini) and reinstall fresh.
