VMs Not Remembering Settings

[I picked this name]

Been using VirtualBox for a while, so I've got the basics down pretty well. I noticed that each of my VMs were unable to store some types of temporary data. For example, I use a VPN on each of my VMs. I can connect through many different IPs with this VPN, and there's a feature that allows me to auto-connect to the last IP address I connected to. The VM remembers whether or not I have this particular feature enabled but doesn't remember the server I connected to last. Same with graphics settings on games. A game I test-ran on the VM will always ask me to set up my graphics options even if I've set them up in a previous session. Neither of these issues happen on the PC I run the VMs on. Any ideas what is causing this? Potentially temporary files being cleared after the machine closes? I'm running Windows XP on the VMs and Windows 7 on my main.

The settings you mentioned would be saved in your XP guests, not by VirtualBox. I would do a search for settings not saved Windows XP.

There is a possibility to set Virtualbox in such a way that guests don't remember any new data.

A quick test: If you make a new text document on your guest desktop, then shut down the guest completely, then reboot the guest, is the new text document still there on the guest desktop or has it disappeared?

True but the OP states it is only certain settings that are not saved, not that it doesn't save any.
