Hi James,
Thanks for that, it brightened up the day!!
The real reason I was asking- we have a few lightly used desktops, and a few backup laptops. All of our regularly used PCs and laptops will be Win7 by that time, but we will still have a few XP Pro machines in (potential) use.
So I will keep a fire extinguisher handy, in case of spontaneous combustion!

One thing you can do to hedge your bets is pull an image of those XP machines so that you can do a bare-metal restore if fire breaks out.
Another approach is to swap those machines to CENTOS and convert the XP to a VM on that hardware. In the enterprise space that is the step-wise progression where there are apps/systems that can't move from XP yet. Re-spinning an XP machine from the latest good image only takes a few minutes.
