The vast majority of times when I post tips to software, the respective product is free. However, just because it is ‘free’ doesn’t mean it has no restrictions as there are different models of free software. The primary ones are freeware, shareware and open source.

It is a good idea to know the difference between these release models. For a good plain English explanation, check out this article. To quote on a brief overview of the differences:

• Freeware is usually a very small program, released by a student or enthusiast.
• Shareware is usually a mid-sized utility or application, written by a professional developer or small software company. The developer or publisher does not have the resources to market it, so they release it as shareware with a “try-before-you-buy” business model.
• Open source spans the gamut, but the largest “free” software out there are all open source–Linux, FreeBSD, PostgreSQL, Apache. Before the advent of VCs in the “free software industry,” collaborative development around a shared code base was the only way a large free application could be built.

Whenever you purchase a new PC from a major computer manufacturer, typically it comes with lots of stuff you don’t want. This is very annoying because you have to either reformat your drive or manually remove each program. For a simple one step solution, check out PC Decrapifier:

The PC Decrapifier will uninstall many of the common trialware and annoyances found on many of the PCs from big name OEMs. Here is the current list of software and items that the PC Decrapifier can detect and remove. You get to see the list of items it detects and then choose what will be removed automatically.

Needless to say, this can be a huge time saver. While I have never personally used it (or had the need to), if anyone has please post your experience.
