This is a really good explanation/trouble-shooting article and guide that is aimed at the average computer user. No geek speak. And it uses current systems and versions with up to date troubleshooting steps and/or tools.
From the article:
Unfortunately, sometimes one or more of those patches will cause a problem, ranging from serious ones like error messages preventing Windows from starting, to less serious ones like video or audio problems.
If you're confident that the problem you're experiencing began only after one or more Windows updates, whether manual, automatic, on Patch Tuesday, or otherwise, continue reading for help on what to do next.
This might also be a good time to look over our Windows Updates & Patch Tuesday FAQ page if you haven't already.
Note: Any of Microsoft's operating systems could experience problems after Windows updates are installed, including Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows Server versions."
