Answer 1

Statistics statistics are different.
You can collect statistics on the site, determining which OS the user came from (be the owner of a popular site to collect enough data)
You can know the statistics of automatic updates from MS (be an employee of MS)
​​Look for ready-made statistics and surveys.
The issue is that the target audience is different everywhere and no one can collect real statistics. For example, companies with tens of thousands of jobs can have windows without access to the Internet at all.
