In recent months Microsoft has made a major change to the way Windows Updates are deployed to both home and business users. This change removes the ability to pick and choose which updates or patches to install and see’s update delivery change to a ‘monthly rollup’ release similar to installing service packs in the past.
This rollup method combines all security updates as well as patches/bugfixes into a single package and is designed to roll Windows up to a later (or current) build number. These incrementing builds can almost be thought of as different windows revisions with each incorporating many major changes as well as introducing a new system build number. This new update strategy currently effects Windows 7, 8, 8.1 and 10.
Systems where Tridium Niagara AX or Niagara 4 is installed are licensed upon initial installation by means of providing a host ID that is drawn from a number of unique variables within the host operating system.
