ou can automate and execute Windows Update with PowerShell script.
This is a simple example script to install and reboot the server after patching.
Feel free to change the last line of the code to not reboot the server after completion if that’s necessary.
If you have Powershell version 5 would be easier.
1) The first thing you need to do is confirm the version of PowerShell you have:
$PSVersionTable.PSVersion
If version 5 or above, confirm you are running PowerShell as administrator and continue with:
Install-Module PSWindowsUpdate
Get-Command –module PSWindowsUpdate
Then you will need to register to use the Microsoft Update Service, not just the default Windows Update Service.
Add-WUServiceManager -ServiceID 7971f918-a847-4430-9279-4a52d1efe18d
Then run:
Get-WUInstall –MicrosoftUpdate –AcceptAll –AutoReboot
Below is the script for other versions other them 5 which is above.
