Users concerned with privacy would not be using Windows, given all of its other known telemetry issues and malware surface. Ie it might already have uploaded whatever was sensitive, even without needing to run a malware examination on it.
Apple and Microsoft products are full prize products, so I fully trusted they don't come with crap. Unfortunately Microsoft alinated their end consumers starting in 2012 with Win8, and Windows 10 and Office365/2016 are well known spying adware ladden. It's telling that Google products, given they are ad-supported, are well behaving and good citizens (e.g. adhere the users privacy settings) while MSFT products released in 2012 (or later) are not. Do like most users stay with Win7 (supported til 2020) and Office 2010, or move away if you can. They won't change except you show them with your money.
