According to Microsoft, checking for updates of Windows 10 is easy enough:
Go to Settings > Update & security > Windows Update and select Check for Updates.
My conclusion: either I am an idiot, or the information presented by Microsoft is wrong. Check for yourself in the screen shot.
If the first is true, then I need help. If the second is true, then Microsoft is wrong. It is bad enough to insult one's customers by not giving them information they require, but presenting them with information that is demonstrably wrong, puts the company squarely in the category of religion, quackery and other forms of swindle.
As always, I welcome replies. If you think I am wrong, please tell me, and tell me why. I love to learn.
