Thurrott is the tech person in his home -- his wife just wants stuff to work so she can do whatever as painlessly as possible... it's not an uncommon scenario, though the gender aspect can of course be reversed. Also somewhat common, his wife was having issues with high DPI display. The higher the display resolution [e.g. 1080p], the smaller any text will appear on that display. Windows has both manual & automatic controls to increase the size that text [and the window that that text appears in] displays. And it's broken -- has been & may always be broken.
One point of the article is that Microsoft revealed perhaps too much information in a blog post [he links to] that appeared coincidentally just when Thurrott was wrestling with the issue. As Thurrott writes, it's not an easy or fun read. The 2nd point was that for apps that aren't universal [in the Windows 10 store], display scaling will probably not ever work the way that it should. Microsoft started working on updating Notepad [a pretty simple app, right?] to scale properly in Windows 10 -- two major releases later [1511 & 1607] & they have it partially fixed.
And they had to make changes to Windows to enable what they got working so far. If they get Windows 10 to the point that app scaling can work the way it should, And make the process of adding scaling to apps workable, they still have to entice developers to rewrite &/or modify their apps to include it. Doesn't sound promising to me either.
Personally I found parts of that Microsoft blog appalling, which is part of why I'm posting this...
The people writing Windows code had not, & to some extent still have not, ever tried to write a program. They build into Windows all the functionality that developers use -- some stuff developers have to use, & some is optional -- but they've never had any real idea if or how well that stuff worked. It's like: we tried using some of this stuff & Wow, it was crap, so we've been working on fixing parts of it -- what a great learning experience!
To me it comes across as clueless -- a characteristic apparently not limited to just the Windows coders at Microsoft, as the folks behind Exchange rolled out unannounced [& buggy] changes, that created chaos with some corp & university email systems until it was rolled back. Sadly some Microsoft & Windows stuff now makes more sense.
