Three Heathrow departure screens have recently shown signs of malfunction: one displayed a Windows activation reminder, another showed pages with dates nine days apart, and a third exposed what looked like Windows 7 beneath the signage. The glitches drew attention from Register readers and raised questions about whether the displays were receiving updates or running ageing software.

The article gives no explanation from Heathrow for the faults, and the apparent Windows 7 identification is based on visual clues, including a network dialogue and the taskbar. It compares the sight of old technology at the airport with the retired Concorde on display there, noting that the aircraft left service in 2003, during the Windows XP era.
