Truecrypt & Deep Freeze

Hi, I'm new to these forums and have some questions about using Truecrypt with Deep Freeze. I could not find the needed information anywhere after hours of searching.

Facts:

1. I've encrypted my entire hard drive with truecrypt.
2. I do not have Deep Freeze or a similar program installed.
3. I recently reset my laptop to its factory settings.
4. I am running Vista, my only operating system.

Questions:

1. Is there an open source alternative to Deep Freeze of equal or superior quality that is compatible with True Crypt hard drive encryption?
2. If not, is Deep Freeze compatible with True Crypt?
3. If so, then what changes must I make, if any, to make the two programs compatible?
4. Finally, what would you recommend?

Thank you for any assistance.
