llewellyn, basically you're running Linux, and Win XP in VirtualBox. That's about it.Not sure how to put this. I'm a trained
MVP Malware removal Expert WinPatrol, or any 'third party Software' primarily is a GUI for accessing Advanced features of Windows. Basically what you are doing is utilising the
MSconfig Utilility, via WinPatrol. Sure Scotty is cool, important however to get to the guts of the system to truly control these Windows utilities.
You can RUN > "services.msc" also and shut off Services such as, Windows Updates, and on, and on. For legal reasons I wont say any more about disabling Windows services.
Black Viper xp-AntiSpy also takes control of some nuisance 'Services'.
The most useful of these "old favourites" is,
ERUNT which takes a Snapshot of your Registry, you install a program, don't like it, run the Erunt Snapshot and your OS will be restored to the state before Installing 'the program.' ERUNT works; Windows System Restore doesn't.
To take it all back home, I believe you running WinXP (Service Pack 3 would be a good idea, latest Drivers, Security, etc.) in a Linux install inside Virtualbox is the Dynamic feature that pleases you.
Say you ran WinXP SP3 outside of Linux, and NOT encased in VB; you'd quite simply be a 'Malware Magnet.'

I've read a few of your threads and you have an imaginative perspective on things, nonetheless, no disrespect intended, I believe you are a Linux Man, and have little understanding of Activating Windows; running Windows, or even what Winpatrol is. Reason I've linked to some stuff is in the hope you may learn something deeper about what you are doing.
I've thrown you a plethora of 'Tools' which you may find interesting; also to the Educated, all these "Tools" have nefarious further functions which I can't speak of here. In fact just knowing the "services.msc", and "msconfig" commands gives access to many things exploited in Windows.
They are also cool utilities for the general Windows User, to save some time tweaking.
A little story about a virus, a broken Modem, and Winpatrol.
I was off line due to my Modem giving up; whilst waiting on delivery the next day for a new one I realised I had a Virus. Odd situation as I've never had a Windows Virus; without being able to go online I felt what a great opportunity to play with this Virus. I used Winpatrol to stop it starting. I noticed in 'Startup' programs once stopping the infected program(Trojan) that each time I stopped it starting a new program appeared. Viruses change their name, they do all sorts of amazing things, to the point when I was cleaning Malware we renamed our removal tools, as the Malware is programmed to identify the removal tools.
Sorry about all that, however I felt llewellyn may find my stories of interest.
