'Minimem', and 'FreeOTFE'

Minimem

Minimem can reduce the memory footprint of any application. It runs in the background and can be set up to optimize as many proceses as you'd like, using a very intuitive graphical interface. Unlike other memory optimization tools, it gives you full control over what applications you want to optimize, when and how often. It optimizes memory by removing as many non-necessary memory pages as possible from the selected processes. It does so at regular intervals which can be user-defined as well and every 30s by default. This then optimizes your applications which can load those pages back whenever they need, and makes your overall system perform much better whenever it is memory limited.

FreeOTFE (On The Fly Encryption)

FreeOTFE is a free, open source, on-the-fly transparent disk encryption program for PCs and PDAs. Using this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.
