One of the essential ways to stay safe from a number of online threats is to keep your software updated. Software updates close security holes and can even offer performance improvements. Of course, a lot of people don't bother to update their software, which leaves them vulnerable.
That's why for Windows 10, Microsoft decided to go with mandatory updates. When an update comes through, it gets installed at the first available opportunity. While the intention is good, the actual execution has caused some problems, from endlessly restarting computers to known broken updates that users can't avoid. The latter is what came through in the latest update ("Windows 10 Cumulative Update KB3124200") and it's making some people very angry.
An unknown number of people who opened Word 2016 (and some reports indicate other versions of Word) after installing the last Windows Update were shocked to find that all their preferences and customizations, including macros and autocorrect dictionary tweaks, were gone. The Windows 10 update contains an patch for Office that for some reason overwrites the normal.dotm template file that Word uses to record your preferences, so everything goes back to the factory defaults.
If that has happened to you, you can get back your customizations. Microsoft outlines the steps here. If you haven't installed the update yet, you might want to find the normal.dotm file and make your own backup just in case. You can find it by going to Start>>Run (or pressing Windows Key + R) and pasting in %appdata%\Microsoft\Templates and pressing Enter.
Find the normal.dotm file (here's how to turn on file extensions if you don't see a .dotm) and copy it to another folder. Then if something happens to Word, you can copy it back into the original folder. Note that older versions of Word might just have normal.dot, but that shouldn't be affected.
