I like trying out and playing with new programs to see if they have any value for me. What I hate are those programs that advertise themselves as free, but after they are installed, you find they are only trial offers.
That Bait and Switch technique turns me off and generally, I will uninstall the program right then and there. However, I worry about what components it may have left on my computer that perhaps I don't want there.
When I came across Revo Uninstaller, it was a perfect solution. Not only does it uninstall the program, but it is able to scan the drive for any remnants of the program that are lurking around giving me the choice to uninstall them too.
