Microsoft to push automatic Windows 10 upgrades in 2016

"Microsoft has announced that Windows 10 will be automatically rolled out next year to all users of its older operating systems who have selected to receive updates.

Until now, users of Windows 7 and 8 have needed to register to upgrade to Windows 10. But that's about to change: soon the OS will be listed as an 'Optional Update' and -- from 2016 -- a 'recommended' update that will automatically install itself, if users have opted to receive updates in that way.*Shadedshun :shadedshu:

You can opt out of automatic updates to avoid this, but Microsoftsays that "we strongly discourage this in today’s connected world because of the constant risk of internet threats". You can also change your Windows Update settings to install critical updates but not recommended ones. Although it's still going to be possible to avoid installation, Microsoft seems quite determined for everyone to be using Windows 10 in near future.


The roll-out of reserved updates was initially staggered but, according to Microsoft, now Windows "will automatically kick off the upgrade process once you have made a reservation".

As an intermediate stage, Microsoft says that it will "soon" publish Windows 10 as an optional update, not installed by default, but accessible to all users."
