Sandboxing? [SOLVED] I'm not 100% sure it's a sandbox program I need, but basically I want to be able to load up an XP program within Windows 7 without it being able to affect my Win 7 installation, and thought a Sandbox would be what I need, but those I've looked at tend to seem more related to specific programs themselves e.g. browsers, audio players etc. So really just wanted to get some info & also some suggestions of appropriate (free) software to sort me out . Thanks.
