The question
Where could I find information or statistics about, how many people change their size of text, apps, and other items in Windows 10?

The story
When installing Windows 10, the default zoom-rate of text, apps, and other items size is set to 150℅. A colleague of mine expressed concerns that a lot of people might not change this, which would result in some complications for our webshop. Our target audience is very broad but consists mostly of parents in their 30-50.

Apart from the question above, I’d love to know if any of you guys take this into account when designing?
