One little problem with this method. If you apply these settings I noticed that hovering over taskbar running app icons you only get the balloon (if switched on) and not the toasters. Like winamp not toasting the play controls, explorer not showing the active explorer windows toast, etc.
Has anyone fixed this? (desktop window manager service enabled/disabled made no difference)
EDIT: OK, just found out that IF you have single click select on and leave default mousehover values, you can get explorer to not select the files when hovering over them. BUT you need to use "Use check boxes to select files" or in the registry "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\AutoCheckSelect dword 0x1"
