A customer reported a Windows bug via Feedback Hub. It said that after signing in, they got this mysterious error message:<\/p>\n

The customer included a screen shot but no diagnostic information or process dump files. This is all you get:<\/p>\n

You are now in an episode of CSI: Crime Scene Investigation<\/a>. The investigator has only a tiny piece of physical evidence and must use it to track down the killer.<\/p>\n

Can you solve it?<\/p>\n

\u00a0<\/p>\n

Look closely at the taskbar. The button for the error dialog has an unusual icon.<\/p>\n\n\n\n
\ud83d\udcf7<\/td>\nError<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

It’s a camera, which happens to match the camera icon on the desktop for Contoso Camera<\/i>.<\/p>\n

This error dialog didn’t come from Windows. It came from Contoso Camera. The customer can take up the issue with Contoso.<\/p>\n

Now, it’s entirely possible that something in Windows changed that caused Contoso Camera to run into problems, but we’ll let the Contoso Camera folks take a crack at the problem first, seeing as they understand their code better than we do.<\/p>\n
