I think it may be dawning on them. I'm on an international holiday & didn't get time to faff about installing Linux before I left. But I discovered the day before my flight that Microsoft has extended its offer of security updates for another year to individuals as well as businesses free of charge, and signed up. Last time I'd looked I'm sure ESU was for businesses only.

The bit that made me laugh was: "ESU enrollment does not provide other types of fixes, feature improvements, or product enhancements." Phew!

I'll crack on with upgrading to Linux when I get home, nice little winter project.
