well you could uninstall the update that added it. [simple google search will tell you that] or you could go to the dir and delete the exes. C:\Windows\SysWOW64\GWX & C:\Windows\System32\GWX [can't remember if its GWX but it is a 3 letter folder starting in G :L] There are some other files to delete but I've forgotten them main exes in those dir's tho.
