Windows: Enable Visual Styles for a modern look-and-feel
Windows: display a wait dialog during the lengthy opening of a volume. There is still a freeze in the GUI even though the call to DeviceIoControl is done in a separate thread which can't be explained. Maybe if we had an asynchronous Device Driver call, things would better.
Windows: Enhance performance by implementing the possibility to choose the correct hash algorithm of volumes during various operations (mount, change password...). In case of system encryption, slightly speedup Windows startup time by making the driver pickup the correct hash algorithm used for the encryption.
