There is a great little tool in Windows Vista that maybe missed by many people and I dare say it is available in Windows 7.
It is called the Snipping Tool. What it allows you to do is select a section on the screen and save it as an image in jpeg format. What I have found it good for when watching a webinar that the presenter may not save a permanent link to but you may want to be able to save it as a way of a reminder to review the information.
I just create a Folder and as the webinar progresses I do a snip of the screen and save it into the folder.
