How to download and install the August 2016 security updates
All security updates are made available on Windows Update. Windows home devices are configured by default to use Windows Update.
Depending on the configuration, updates may be downloaded and installed automatically.
The check for updates does not happen in real-time though. If you want to grab the updates right when they become available, do the following:
- Tap on the Windows-key on the computer keyboard, type Windows Update, and hit enter.
- This should open the Windows Update dialog. Windows may run a check for updates automatically, or after you click on the "check for updates" button or link.
Updates that are found are either downloaded and installed automatically, or on user request.
It is recommended to research all Windows updates before installing them on productive machines. The reason for this is that updates may break functionality or in the worst case prevent the system from booting at all.
It is recommended to create a system backup prior to installing updates as well.
