Hi, I am not very experienced with Oracle VM VirtualBox.

Is it possible to extract a file from my Windows XP VM so that I could use it with a real version of Windows XP?

If you have Guest Additions installed in the XP guest, then you can use a Guest Additions Shared Folder to pass the file from the guest into a folder on the host, then move the file from the host to wherever you want it. See https://www.virtualbox.org/manual/ch04.html
