Missing foo (e.g. battery) icon in Vista taskbar

With reference to this post,

I encountered this problem last night, on a Vista installation. Right-clicking the taskbar, then selecting Properties -> Taskbar and Start Menu Properties -> Notification Area -> System Icons -> Battery does not work, because the check boxes are greyed out.

The easiest solution is to hit Ctrl+Alt+Del, bring up the Task Manager, and then restart explorer.exe. Here’s the solution that I’ve directly taken from Akshit’s reply to that thread:

  1. Go to Task Manager.
  2. Go to Process tab.
  3. End the “explorer.exe” process
  4. Go to Applications tab
  5. Select “New Task…”
  6. Type “explorer.exe”

Hope this helps somebody, as Akshit’s reply was about halfway down the thread.
