Updated changes to Automatic Updates in Windows 8.x
November 26, 2013 Leave a comment
On computers running the RTM release of Windows 8 and Windows Server 2012, Windows Update no longer defines when to install updates. This is now the job of Automatic Maintenance, which is used during the minimal activity during active computer use [i.e. 4AM or when you step out].
Windows Update on Windows 8 and Windows Server 2012 computers also has new restart logic that defaults to forcing a restart 3 days after the installation of updates instead of 15 minutes.
To avoid unintended data loss, forced restarts will no longer occur if a user is not actively using the machine, able to see the restart notice, and save their work.
This update is already included in Windows 8.1 and Windows Server 2012 R2.
Most likely, if you have kept up with the updates from Microsoft, you should already have this update installed as it was released in October.
You can find more information at here. Group policy and registry settings are available to tweak the update.
