Hi my friends, I need your recommendations for the best options I can do. Here is the situation: I will do educational screen casting video for some projects and I can not afford the price of the software tools I will need. So I thought to use a virtual machine and then install the trial version of the software I need and when trial expired I can redo it once again. So now I was wondering what is the most light weighted version of windows I can use? Shall I go for VirtualBox or VMware? or there are another alternatives? How to handle the restore of the virtual machine so when I open it it should include all trial software I want installed without reinstalling everything once again to start the trial period once again. I do not know what is the right term for the virtual machine, is it a snapshot or what? and how to make the best use of it? Thanks
