The traditional way of encrypting/ decrypting a file or folder in vista is by right clicking the file – selecting properties – going into the general tab – clicking advanced then selecting Encrypt contents to secure data. Too much work right? here a simple registry hack to make encrypting and decrypting much more easier by adding the encrypt/decrypt feature on your right-click menu.
The first step is to open you registry editor by clicking start (Vista Orb) and typing regedit on the search box. Then Find the following registry key.
In the right-hand pane, create a new 32-bit DWORD, name it EncryptionContextMenu and give it a value of 1.
Close your registry editor.
You should now be able to see a “Encrypt” option when you right click a file.
NOTE: This trick will only work on Vista Ultimate and XP Pro.
