Sandboxie Plus 1.18.1 / Classic 5.73.1 Released

Sandboxie Plus 1.18.1 and Sandboxie Classic 5.73.1, refining how sandboxed files stay in sync with the host system in this free, open-source app-sandboxing tool for Windows.

What's New in Version 1.18.1 / 5.73.1

Added

• New CopyNewer file migration rule that refreshes an existing sandboxed copy of a file whenever the host version is newer, only replaces contents of matching files already in the sandbox, leaving new files, directories, and deleted items untouched
• Option to use GUIDs as box names

Changed

• The Chromium_Elevation template now uses a specific RunServiceAsSystem=... entry instead of the broader RunServicesAsSystem=y, with more service names added
• SandMan's INI setting validation and auto-completion got smarter, disabled-setting aliases, localized descriptions, context-aware warnings, and template-specific tooltips

Fixed

• Incremental update mechanism failing to copy new files
• Conflict between RunServiceAsSystem=... and UseSecurityMode=y
• cryptsvc service failing when RunServicesAsSystem=y was set
• SOCKS5 proxy password authentication failures caused by unsafe credential decoding and encoding issues

About Sandboxie

Sandboxie lets you run a browser, or any other program, inside an isolated sandbox so changes made during that session never touch your real system — ideal for testing untrusted software or safer web browsing. It's available as Plus (modern Qt UI, actively developed) or Classic (legacy MFC UI), both sharing the same core security engine.
