Meltdown and Spectre update not being found

I have multiple servers and workstations are windows 10
Server 2008 R2
Server 2012 R2
Server 2016
Windows 10 both 1607 and 1709
When I check for updates, the windows update check comes back saying no updates available .

Yet I'm looking at different websites and it seems the following KB's should be installed , yet I don't seem to find these KB numbers
Windows Server, version 1709 (Server Core Installation)  KB4056892
Windows Server 2016 KB4056890
Windows Server 2012 R2 KB4056898
Windows Server 2008 R2 KB4056897
Windows 10 KB4056892

Maybe they are not being installed, maybe they are.  I'm hoping someone can give me some information on whether or not my servers and workstations are now protected from Meltdown and Spectre and why the updates are not being found when I choose to look for updates.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Hi,

Not sure why you aren't able to see those updates. It's uncluded in the January 2018 updates. If you are unable to find, try the update catalog
http://www.catalog.update.microsoft.com/Search.aspx?q=KB4056898

KB4056898 is an example, you can download all desired updates.

PS - before applying the updates, you need to check with your AV vendors that your AV is compatible with MS patch? if not, don't apply as your servers get BSOD.

Registry key was needed and I checked with AV vendor.  My Antivirus is supported .  
Thanks for the help in pointing toward the AV.
A co-worker is working on the windows 10 side, so the windows 10 is not a problem at this time.
