It seems that WSUS isn't smart enough to know which updates are actually appropriate for Windows Server Core installs. For example, WSUS wants to install Server 2012 R2 Update (
KB2919355) but it fails (gave it a shot but didn't have confidence it would succeed.) And WSUS believes there are still 14 updates this server needs. Four of those are Silverlight.
Now, I don't truly know whether Core edition needs Silverlight (that's sarcasm) nor do I know whether the recent "Update" for 8.1/2012 R2 is needed for Core (not sarcasm) but on the surface it would appear to be inappropriate.
I'd rather not let this server live its life as continually having need for 14+ updates and 1+ failed updates.
Thoughts on how to handle this? I'm a bit surprised that MS has not made better accommodations for handling updates on Core since that's what they are pushing.
I've learned a few things.
- KB2919355 installs fine on a 2012 R2 Core server. Just make sure you have plenty of disk space available! (ha)
- The server itself knows better when it comes to which updates need to be installed. In the case of Silverlight, WSUS reported that my Core server needed them even though they were set to "Not Approved" and when it came down to it the server didn't have them on its list of needed updates. As it stands, WSUS says the server still needs 4 updates but this is inaccurate because they are all for Silverlight.
