In my case it does not work. I have windows 8.1 pro x64. I created a shortcut to tcc.exe on my desktop. From there, I drag and drop it on the task-bar. Every time I update, the icon in the task-bar becomes blank. If I click on it, it appears a message that asks if I want do remove that non working link. It does not matter if I choose yes or no, the link is deleted. The link on the desktop is still there and still works, so I simply drag and drop it, until next update...I'll try that but I'm not confident.
