I’ve used the SnagIt application for years to do screen grabs and the like. Whilst freeware tools are popping up doing something similar, I’ve stuck with it and recommended it to others. Whilst there was a small licence fee to pay, I bought it years ago and so it’s a sunk cost.
However, the company behind it, are pursuing a new strategy to lure in customers which involves making available old version of the software for free, in the hope you may decide to upgrade subsequently. The details of how you can get version 7.2.5 can be found here, with version 8 being the latest release.
In addition Techsmith are distributing free Camtasia Studio licenses, an application which is great for creating online screen tutorials/demos.
