Replacing the Windows 7 Network Indicator
One of the things missing from Windows 7 is the network activity indicator in the system tray. It's been replaced with a static icon, supposedly to reduce power consumption on laptops and reduce visual clutter.
I'm not sure I believe the first reason, and the second is invalid because it could be left disabled as it was by default in Windows Vista.
Nevertheless, I've written a tiny .NET replacement for the icon. It's not identical - it's more visual than the original icons. It's also configurable so that the two indicators can show disk or disk activity instead of the network, or show error-type conditions - for example, show the light if the CPU is running at more than 95%.
The download is attached to this post - it's a small MSI. It's really an early beta version, but seems to run OK on my Windows 7 workstation and on the Vista development workstation I built it on.
Please post any bugs in the comments!
