Windows 7, released in 2009, was celebrated for its performance and user-friendly interface. However, a peculiar issue emerged: setting a solid color as the desktop background led to a 30-second delay during startup.

The Issue Unveiled

Users reported that after logging in, the system would display the Welcome screen for an extended period before transitioning to the desktop. This delay was consistently observed when a solid color was chosen as the wallpaper.

Technical Analysis

Veteran Microsoft engineer Raymond Chen provided insight into the problem. He explained that Windows 7's logon system awaited signals from various components, including the desktop background, to indicate readiness. When a solid color was set, the system didn't receive the expected signal, causing a timeout and the subsequent delay. (pcworld.com)
