I know XP should not be used on a normal internet-facing PC. But if you run it within a sand-boxed VM that can't access the main PC, is that OK?
My use-case is I run a VPN within a VM, to RDP into a remote PC I work on. I do it through a VM so the VPN only affects that RDP so my regular web usage doesn't get routed through their network.
I have lots of XP licenses - and XP Mode in W7 - and none spare for other Windows versions. So I wondered if the XP VM is only used for RDP access, if this is 'safe' even if the OS did somehow get compromised (unlikely as I never browse the web from the VM)?
