Why does the Magnifier utility start automatically whenever I boot my Windows 2000 or later machine?

A. If you don't stop the Magnifier utility before you shut down your computer, Windows assumes that you want to use the utility the next time you start your computer and automatically runs it (the OS does this by adding the utility value to the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce registry subkey). To stop the Magnifier utility, hit Ctrl+Alt+Delete to open the Windows Task Manager, select the magnify.exe task from the Task tab, then click End Task.
