While Microsoft's rollout of Windows 10 has generally been successful, it hasn't been without its fair share of controversy. From upgrades that change users' previously selected defaults to ones that quietly change security and privacy settings. But perhaps the most reviled part of the Windows 10 upgrade process is the nagware notifications that have plagued and irritated users to no end. Good news: Microsoft will be putting an end to that in about two months. But not because they've finally listened but because Windows 10's free upgrade is ending anyway.
