Sandboxie

Run programs in a sandbox to prevent malware from making permanent changes to your PC. Sandboxie allows you to run your browser, or any other program, so that all changes that result from the usage are kept in a sandbox environment, which can then be deleted later.

Sandboxie is a sandbox-based isolation software for 32- and 64-bit Windows NT-based operating systems. It is being developed by David Xanatos since it became open source, before that it was developed by Sophos (which acquired it from Invincea, which acquired it earlier from the original author Ronen Tzur). It creates a sandbox-like isolated operating environment in which applications can be run or installed without permanently modifying the local or mapped drive. An isolated virtual environment allows controlled testing of untrusted programs and web surfing.

Sandboxie is available in two flavors Plus and Classic. Both have the same core components, this means they have the same level of security and compatibility. What's different is the user interface the Plus build has a modern Qt based UI which supports all new features that have been added since the project went open source. The Classic build has the old no longer developed MFC based UI, hence it lacks support for modern features, these features can however still be used when manually configured in the Sandboxie.ini.

Sandboxie Plus 1.17.0 / Classic 5.72.0 release notes:

Added

added icons to Sandboxie service applications #5160
added name of sandbox in the border #3746
added global option 'ForceBoxDocs=y', allows to force all programs opening a file from a boxed path to the appropriate sandbox
added new box border mode 'all', when active the border is shown for all windows of sandboxed processes, not only for the one in focus
added missing serial number support to SbieCtrl
added mechanism to export/import multiple boxes at once
added UseAlternateIpcNaming=y instead of using a separated NT Object namespace in this mode sandboxed objects get a name suffix
Note: this mode can only be used with App Compartment boxes, as else the sbiedrv would block the accesses.

Changed

validated compatibility with Windows build 28020 and updated DynData
when 'UseCreateToken=y', we always use 'CopyTokenAttributes=y' to fix UWP issues
to force 'UseCreateToken=y', 'SandboxieAllGroup=y' is the new default
'NoUntrustedToken=y' can now be set in box options
reworked LPC server implementation in SbieSvc, to-do: switch to ALPC
improved App Compartment IPC handling
improved RenameSection handling to preserve comments and original section order #5220

Fixed

fixed failure to mount registry when starting a UWP application sandboxed
fixed API CryptUnprotectData always returns a wrong ppszDataDescr #5191
fixed handle leak in SbieDll.dll
fixed the issue with switching sandbox sorting in the view #5201 (thanks Catreap)
fixed Microsoft Edge 144 crashes in Application Compartment boxes #5188
fixed File Searching bar crash when performing multiple searches within a sandbox #5166 #5221
