In multi-user environment it may be important to disable access to some of WinRAR functions for security reasons. If you need to do it, create Registry key:
HKEY_LOCAL_MACHINE\Software\WinRAR\Policy
or
HKEY_CURRENT_USER\Software\WinRAR\Policy
Key in HKEY_LOCAL_MACHINE has a higher priority than in HKEY_CURRENT_USER.
This key may contain the following values:
| Value name | Value type | Description |
| Menu | DWORD | If set to 0, disables WinRAR main menu. |
| Settings | DWORD | If set to 0, disables "Settings" dialog, "Import/Export settings" commands and toolbar context menu. |
| Password | DWORD | If set to 0, disables change of archiving password. It may help to avoid encrypting of important data. |
| OrgPasswords | DWORD | If set to 0, access to "Organize passwords" dialog is disabled. It does not disable access to passwords already stored in this dialog, so you may need to delete them before setting OrgPasswords variable. |
| Shutdown | DWORD | If set to 0, disables "Turn PC off when done" archiving option, so a user cannot shutdown computer. |
Note that policy key does not affect the console RAR (rar.exe file), so for better security in multi-user environment you may need to delete rar.exe and keep only winrar.exe.
Also you can override the location of %APPDATA%\WinRAR folder, specifying a new path to WinRAR supplementary files in string value "AppData" of HKEY_CURRENT_USER\Software\WinRAR\Paths Registry key.
