Andy Bailey, a reader of Register, describes a ride at Alton Towers, a UK theme park, that was formerly named Duel but has been changed to a ghost train experience. During the ride, he encountered a Windows error message stating "Memory could not be read" in explorer.exe, which he found unsettling. The error could be due to failing hardware, a problematic driver, or a code glitch. He reflects on how a truly frightening experience for IT professionals might include scenarios like encountering Windows' Clippy as an undead AI assistant or facing unexpected Windows Updates that disrupt the ride.
