A new icon has appeared in my tray in Windows 7 recently - a black square with a white A in it:

enter image description here

It doesn't have any tooltip or right-click context menu so I haven't been able to identify which process it belongs to. I tried using the "Find Window's Process" tool in Process Explorer but that won't identify individual tray icons.

Short of killing processes until it disappears, is there a good way to identify which process this icon belongs to?

I wanted to keep the question as general as possible, but if you recognise that specific icon please leave a comment telling me what it is! Thanks. – Mark Nov 13 '12 at 16:32
I believe it is part of your keyboard drivers. Try enabling caps lock, and see if the icon changes... – francisswest Nov 13 '12 at 16:34
Maybe check your startup programs to narrow down what it could be? – ernie Nov 13 '12 at 16:35
Spot on - thanks Francis! If I toggle Caps Lock on then off again it disappears. After that it appears (not always, but a bit haphazardly) when Caps Lock is on. Thank you! – Mark Nov 13 '12 at 16:36

Click the up arrow in the system tray, and select Customize. It'll list all the icons and the programs' names.

@Mark: What is the name of your mysery A icon? – FiveO Apr 25 '13 at 12:39

Use Control Panel / Notification Area Icons to identify the icon.

This Windows System Tray Scan Utility may work, though it doesn't mention win7 compatibility.
