User Accounts Settings
This settings page can restrict use of this sandbox to specific user accounts. The Add User button opens a standard Windows user account selection dialog box which can be used to find and select specific user accounts. User account groups may also be specified.
A sandbox that has been restricted to specific users is considered hidden to all other user accounts. Those other user accounts will not see the sandbox listed in Sandboxie Control, and Forced Programs and Forced Folders settings will not apply to those user accounts.
