The problem is that Windows XP is good enough for desktop IT regardless of what Microsoft wants us all to do (Clouds darken outlook for Vista's successor, www.computing.co.uk/2230864). There is even a 64-bit version.This is the problem with the running of commercial IT - the cloud and the servers already account for two per cent of global emissions of greenhouse gases and this is growing year on year. Microsoft is becoming a danger to carbon emissions targets and must rewrite the operating system to have a smaller footprint and fewer powerful processor requirements.

I doubt it will happen, but it will only take 30 years to guarantee the disintegration of both the polar ice caps. Who realised that in IT, I wonder.
