You may not aware the built in file encryption utility available with Windows Vista. If you want to use this utility frequently, you can add this option to the contextual menu (the menu that opens on right-clicking a file). This would make it quite easy to encrypt or decrypt your files ,rather than using the file properties dialog box.
To add the encrypt option to your context menu
- Click ‘Start’ and type ‘regedit’
- Navigate to ‘HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced’.
- Right-click on the right pane and select ‘New | DWORD 32 bit Value’.
- Name the new key as ‘EncryptionContextMenu’.
- After the creation of key, change the ‘Value data’ field by double-click it and enter the integer ‘1’
- Close the registry editor.
Now whenever you right click a file,there you can see ‘Encrypt’ option in the contextual menu.
