There are the so called snapshots, which you can make and then include in
your back up. No need to down the VM.
There is also generally no problem with licenses after reinstall as soon as
you have your activation key or the OEMs disks/dvds. On most computers sold
with windows the key is a sticker somewhere at the back, bottom or
