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. |
| 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.
