Windows 7 Login Delay Mystery: Solid Color Backgrounds Are the Culprit?
2025-04-29
The author, a long-time user of solid color backgrounds since Windows 95, discovered a 30-second delay on the Windows 7 welcome screen when using a solid color wallpaper. This isn't a longer login time, but rather a timeout triggered when the system waits for a signal indicating wallpaper loading completion. Solid color backgrounds, lacking bitmap information, prevent this signal from being sent. A similar issue exists with the "Hide desktop icons" group policy, where a coding error prevents the ready signal from being sent. Microsoft fixed this in Windows 7 a few months after its release. The author also explains their preference for default settings, simplifying bug reporting and resolution.
