How could information leak onto the unencrypted Windows Partition?
If the software you are using was written for Windows XP or later then it is very unlikely that any information will leak out using the system described in this howto. All user data in newer software saved to the hard disk will goes into the users ‘Documents and Settings’ folder, which will be encrypted. Temporary information will be kept in RAM (and so be wiped at shutdown), or in the encrypted pagefile. However software written for Dos/ Windows 95/ 98 etc may save temporary data to its own folder on the C drive, so when using legacy software check on temporary file settings, check to see what it saves to disk (maybe it won’t be secure data) and see if you can install it on the encrypted drive.
