Updating windows 2016 core
At least you could automate this process using Power Shell, but I believe only a very small percentage of Hyper-V customers have meaningfully deployed (although sales figures will differ) SCVMM.
Other Mac Guver’ed solutions existed, including using System Center Configuration Manager to deploy the MSI file from VMGuest.
Check the one(s) you want to install and click the Install Updates button.
After installation you are asked to reboot the server. After reboot the server will be fully patched containing all the security and critical updates.
This tools is great because you have a nice GUI where you can see all the updates, but there are situations where you can’t run it.
You like server core, I know, I like it to sometimes, especially when there is a domain environment present and you can centralize everything.If you want to check only for recommended updates go ahead and press R, but I I usually go for all. Checking for updates will take a few minutes and at the end you will be presented will all the available updates that apply to the server.Also, you can choose to revoke the operation and not install any updates, install just a single one or install all. Another way to check for updates and install them is to use a tool like Core Configurator for 2008 R2 or Corefig for Windows server 2012/R2.After all the updates were installed you will be asked to reboot the server, so click Yes on the message box button to do so. Just mount the ISO (if you are using the ISO version of the utility not the ZIP one) and run Start_or Start_depending on which of the two utilities are you using.As you can see, you can change a lot of settings in the OS using this tool, but since we are interested in updates only, click the Control Panel button then Windows Updates.
