Configuring preferences and options in Outlook.com
When you click on MS update number, it obviously takes you to MS website, where update is explained with link to download.
However, you should not take this "manual approach" too seriously, as this is always the same when you investigate MS updates.
99% of MS updates are fully AUTOMATIC and as far as I know, the only way to know if you have it installed or not is to check INSTALL/REMOVE Programs and go through the list. Whether such a list goes back to 2012, I kinda doubt, but ya never know.
