I've been using VirtualBox for a while to virtualize Ubuntu inside Windows 7. Now I'm wanting to make a Windows 7 guest sandbox inside a Windows 7 host to install experimental software and tweak settings without fear of crashing my primary OS.
Before giving this a try, I wanted to know if it is possible and even legal under Microsoft's terms?
Secondly, is there a better (free) way to make a sandbox for the same purposes?
