Last week, we reported how Microsoft had quietly removed deferral options from the Settings app - something that wasn't announced by the company and was only discovered hidden in the documentation for IT Pros. Since this option is used to avoid a new Windows 10 feature update until it's stable enough, the change didn't sit well with many users.

In the document, Microsoft had mentioned that it was making this policy change "to prevent confusion." Since the user uproar, the Windows maker has clarified exactly how this policy change does actually manage to prevent confusion - at least to some extent.
