If this issue is inconveniencing you, you are also able to temporarily or permanently hide specific applications from your software list. To do so, locate the application on your list and click the "Expand All Info & Settings" tab. You may choose to either "Hide" a program, which permanently moves it to your Hidden list, or "Skip" the program, which removes it from your list until the next version is available.
If the item is on your "Download Watch List", you can remove it from this list also, which is located under the "My Profile" link in the upper right corner of the TechTracker home page.

I have deleted a program I do not want but I am still getting notifications that there are updates for the deleted program. How do I delete unused/deleted programs from Tech Tracker?
