Once again, building upon my previous post, Determine if an Update has been Installed or Not, I transformed my initial IsQuickFixNoInstalled() function into a more versatile function to list all the updates installed. One could easily use it to populate a listbox or output its results to a text file for easier review.

Do note that the function takes a couple seconds to return a value.
