Microsoft Facing IT Manager Resistance to Automatic Windows 10 Updates
Found on eWEEK on Saturday, 07 November 2015

Many corporate and business users—particularly IT managers—are all concerned about the havoc that the update might wreak on the performance of their applications and computers.
Microsoft responded in a blog post by Executive Vice President Terry Myerson explaining the existing options for upgrades and also revealing that, starting next year, Windows 10 would be installed on Windows 7 and Windows 8.1 through the normal update process.
Sorry, but no. The only option left then is to completely avoid the updates and sit on unsupported operating systems, just like XP; which is still the workhorse behind some not so obvious systems, like banking terminals. The last thing you would like is a nightly reboot of an ATM machine after which the UI does not work anymore, making it impossible to withdraw money. Or worse, it could allow attackers to gain access to the bank's network. Microsoft is on its best way to alienate their most-paying customers. If you cannot safely predict (and test) the state of a system, it is worthless for development.
