If you are a Windows user then at some point your Explorer is bound to CRASH sometime. The worst thing about Explorer crash is that whenever your Explorer crashes, all the icons on the tray will vanish.
Under normal conditions you need to restart the system to recover the lost tray icons, but with YTrayMagic this process is automated.
YTrayMagic has the capability to detect an Explorer crash (this is done automatically) and it starts working as soon as it detects a crash and it restores all the lost try icons for you.
Works like charm on all Windows 9x systems.
