Windows updates with Windows 10 are basically ‘set and forget’, they are automatically set when Windows 10 is installed. Updates can take a long time to install and can auto reboot your machine. Most of the time this can be scheduled but very occasionally it will warn you and reboot no matter what you are doing, particularly if you have postponed the update for a period of time.
The machine needs internet connection and can use 3-4 GB at a time – this is most commonly happens when a new build release is offered by Microsoft. These updates can take a long time to download and slow your connection down if the machine is not connected to a VDSL or Fibre connection. You can also check to if updates have been applied correctly by looking at the history of Windows Updates.
Windows 8.1 and Windows 7 updates are less intrusive and smaller, but equally as important.
Note: Windows 10 is a service, which means automatic updates are turned on by default and your PC always has the latest and best features.
