The UK Department of Work and Pensions had computer problems earlier this week leaving many people without access to benefits. It turns out that when they upgraded 7 PC’s from Windows 2000 to Windows XP it caused a BSOD (crash) on 60,000 other PC’s. I’m sure that Microsoft won’t find this amusing as they are currently trying to get people to switch to XP while they work on their next gen OS, Windows Longhorn.
