Key features of the TTCS OSSWIN CD

Easy to install
Many Free and Open Source Software for Windows are made available as ZIP files which require the user to manually extract the files to a directory and then use Windows Explorer to browse to the directory and run the program. The TTCS has created standard .EXE installers for these applications, using NSIS. This allows the user to easily install and uninstall the program.
Easy to browse with Windows Explorer
All of the software on the TTCS OSSWIN CD is in the "Software" folder with subfolders for each of the categories. This makes it easy for those users who are familiar with the CD to use Windows Explorer to browse and install software on another machine.
Software on the CD is up to date at time of purchase
The TTCS OSSWIN CD is burnt "on demand" for upcoming TTCS meetings and/or email requests to purchase the CD. Buyers receive the most recent stable versions of the software at time of purchase.

What is Free and Open Source Software?

Free and Open Source Software is software for which the "guts" of the program can be freely downloaded and altered to suit your needs (provided you can do the programming). There are many types of Free and Open Source Software. The difference lies in the way altered versions of the software can be distributed, so, if you customise the software for your own needs, then decide to distribute it, you may be bound by specific terms.

Many Free and Open Source Software projects make ready to install executable versions for various operating systems including Windows.

You can do the following with Free and Open Source Software :

  • Install the software on any number of machines in any environment (home or commercial) without purchasing licence fees for each machine.
  • Obtain and modify the source code and distribute modified versions of the program together with the modified source code. Free and Open Source Software licenses differ in how such source code can be distributed or licensed for others to also do what you have done.

Here are several links for you to learn more about Free and Open Source Software :
