LiberKey is a system for installing and keeping updated over 300 free programs (both open and closed source) on a Windows machine. All of the programs are portable meaning that they can run directly off a USB key without installing anything additional on the computer (this is very useful if you’re working on a computer where you don’t have administrative rights). The programs are organized into the following categories: audio, CD/DVD, education, file management, games, graphics, internet, networking, office, security, system utilities, and video. One great feature Liberkey has is the ability to
temporarily change file associations. Here is the
full list of programs available.

Microsoft Mathematics is a free
Computer Algebra System (CAS) available from Microsoft. A
CAS is a program that can solve purely symbolic mathematical equations. For example, the program can tell you that the derivative of 6x^2 + 12x is 12x + 12. The program has functions for calculus, statistics, linear algebra, and graphing. One interesting feature of the program is that in some cases it can show and describe the intermediate steps involved in solving an equation. Here’s a
16 page tutorial (in MS Word docx format) showing how to use the program. The program can be downloaded from the
Microsoft download page. Thirty-two and sixty-four bit versions are available. The program only works on XP/Vista/Windows 7.
