For those of you who run GNS3 and/or Virtual Box or VMware and would like to have a free legitimate Windows image, Microsoft Internet Explorer team has provided an answer! Did I mention it is free?
Don't believe me?
You can download different versions of Windows with different versions of Internet Explorer for free! The idea is to let you have a 90 day ability to test. These images are available for Windows, MAC or Linux machines.
You can easily get around the 90 day by creating a clone of the machine once you have it installed, and then reinitializing the clone!
There are full instruction on the Microsoft web site!
