I'm working with a fresh install of Windows 7 Pro. So far, all I had done was:
- Install the OS (on a freshly formatted drive),
- Ran Windows Update, used "Check for updates," and installed all the important updates, then rebooted.
- Repeated step 2 until it didn't find any new updates.
When it was done, I went to customize the Notification Area Icons, and I noticed that Windows Update appears twice, as seen here:
I've seen items get stuck there before, from uninstalled apps, and I've fixed it using Piriform's CCleaner.
So I downloaded and installed CCleaner, checked the "Tray Notification Cache" checkbox, clicked "Run Cleaner," and rebooted.
But it didn't fix the problem. I realize this problem may be purely cosmetic, but I'd still like to fix it if possible.
