In Windows 7 a balloon tip in the tray area let me know when I had updates that needed to be installed. In Windows 8 this seems to be missing or disabled by default. In fact, the only screen I've found which mentions pending updates is the log-in screen.
I even checked the metro start screen and haven't found anything mentioning updates. I'm using Start8 right now to avoid having to use the metro interface.
I prefer to install updates manually when I'm not going to be interrupted by a restart, but without a tray notification I'll never know when I need to. Is there a way to restore the old behavior from Windows 7?
