Why Windows’ Formatting Dialog Has Stayed Unchanged for 30 Years
Dave Plummer, a senior Microsoft engineer, explains how a quick‑made formatting dialog created in 1994 as a temporary fix ended up persisting for three decades, shaping Windows UI and even imposing lasting limits on FAT volumes.
Dave Plummer, a senior Microsoft engineer known for creating Task Manager, Windows Pinball, and native ZIP support, recently recounted on X how he built the Windows “formatting” dialog as a quick “temporary” solution.
In 1994, while migrating massive code from Windows 95 to Windows NT, the existing formatting dialog needed a redesign. Using VC++ 2.0’s resource editor, Plummer sketched a simple vertical‑list interface, choosing a vertical layout so users could tick options in a roughly correct order.
The design was intended solely as a stopgap, not for visual appeal, until a more elegant UI could be delivered.
Surprisingly, this provisional dialog persisted for three decades; even the latest Windows 11 preview still displays the original layout with no sign of improvement.
Plummer warns developers to be wary of the word “temporary” in software projects.
He also notes that his intuitive decision to limit the cluster slack size unintentionally set the FAT volume formatting maximum to 32 GB, another “temporary” choice that became a lasting constraint.
