In Windows Server 2016 there are no GUI options available to change the update behavior.
In this blog I was outline the different ways to change the Windows Server 2016 Update settings.
Windows Server 2016 Update settings
Windows always looks at registry keys located in the following hive:
Typically there is a key named ‘AUOptions’ with a value in the range 2-5, and have the following meaning:
– 2 = Notify before download.
– 3 = Automatically download and notify of installation.
– 4 = Automatically download and schedule installation. Only valid if values exist for ScheduledInstallDay and ScheduledInstallTime.
– 5 = Automatic Updates is required and users can configure it.
You can change the registry key with the help of Powershell directly:
In Windows Server 2012 I used to change the setting using the .NET object as below, this doesnt work anymore in 2016 as the API only allows “GET” statements.
Sconfig is basically a simple batch script, which is sufficient for configuration tasks such as update settings.
In the sconfig prompt you can select options ‘5’ to enter the update settings configuration and then choose:
A – Automatically scan, download and install updates. After installation perform a reboot.
D – Automatically scan, download updates
M – Never check for updates, trigger manually.
Open a command prompt with administrative permissions and run SCONFIG from there.
You can always use the trusted GPO’s in an Active Directory domain environment. The settings are located under ‘Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Update’.
You can configure the same range of numbers here.

Scheduling Day / Time
When you set the update settings to “Automatically download and schedule installation” it could be that you also want to decide yourself which day/time it should update. This can be done using the ScheduledInstallDay and ScheduledInstallTime keys in the registry.
|0||Install every day|
|1-7||Specific day of the week where Sunday =1 and Saturday = 7|
|0-23||Time of the day in 24-hour format|
Setting the Scheduled Install Day to Tuesday:
Setting the Scheduled Install time to 6 AM:
The changes take effect after logoff
