What is stimon.exe?

From Microsoft company: “Still Image Monitor (Stimon.exe) is a tool that is installed by Windows Millennium Edition (Me) and Windows 98 when a Universal Serial Bus (USB) scanning device is successfully enumerated. Stimon.exe enables a USB still-image device (such as a scanner) to initiate data transfer to a program. This is called “push model” behavior. For example, if your scanning device has a Scan button, it may start a program and begin scanning when you press it.”
Windows Still Image Monitor lets you to associate a program, which can work with digital images and scanners to pressing of the “Scan” button, so that this program will get started as soon, as you will press “Scan” button on your scanner. Process stimon.exe also is required by some digital cameras. You will not be able to use your scanner or digital camera, which depend on stimon.exe process, if it will not be loaded into memory, so terminating stimon.exe manually is really a bad idea, especially if your hardware require it to function properly. However, if you don’t have such hardware or your digital camera or scanner do not require stimon.exe, you can safely terminate it and prevent it from starting automatically. Such actions are especially useful, if stimon.exe causes compatibility problems and some of your software doesn’t work as intended, when stimon.exe is running (it is known, that some financial and other software is not compatible with Windows Still Image Monitor).
