Slashdot | Failed Win XP Upgrade Wipes Out UK Government Agency "The BBC and the Register report that the UK Government's Department for Work and Pensions attempted to upgrade seven PCs from Windows 2000 to Windows XP, and ended up with BSODs on over 60,000 machines. I wonder if the National Health Service is regretting awarding Microsoft a £500 million contract now."

hmm. the nhs is a completely seperate body to the UK Government. but how is it possible for an upgrade of 7 pcs to cause such an effect?
