Re: @Dave K
I mean almost all PCs to be honest. MS's LTSC version of Windows 10 is deliberately crippled in many areas to try and dissuade businesses from using it on anything but mission critical shop-floor machines. Your standard office PC will be on the Current Branch for Business, and hence will still get bi-annual "feature updates" even though 99% of businesses couldn't care less about a new version of 3D Paint.
Of course, many of them do care about their PCs being down for 90 minutes or so whilst the update applies, and many of them also care when a handful of PCs break during the update process. Hence my question as to why MS doesn't see reliability as a marketable feature for PCs - home as well as business.
