Is there a way to install programs and make changes to a virtual machine and if they work ok have them applied to the "actual" machine? For example in this question when fiasco_averted says "...only let the person do his work in a VM, then mirror the settings on your own on your machine." is there a way to do this using virtual box?
I'm using Windows 7. The reason I ask is I'm thinking about doing a fresh install and want to get everything set up right.
