How to get rid of the yellow shield in taskbar

I use Windows update to download "Windows Installer v3.1" to my system. But
it can never be installed even I tried so many times. Everytime it failed to
install I restart my PC. Since the program can never be installed, a yellow
shield (Windows update icon) stays in taskbar forever keeps bugging me to
restart my system. Can anybody tells me how to either
1. make the "Windows Installer v3.1" successfully installed to my system, or
2. get rid the yellow shield from the taskbar. Thanks very much for your
help in advance.

I wNT TO UPDATE.
