today I've installed KB4011645 update for SharePoint Server 2016. And now I regret it and wants that update to be removed. Could someone here know how to do that? According to this SharePoint Server 2013 – Can you uninstall patches?, you can't do it.
Edited to Add more information on the problem
I've written my problem to msdn. Here's the problem and summary.
- The problem still exist even after running SP configuration wizard (see point 2nd).
- the problem didn't appear after doing iisreset. Word asked for credential to open the document.
- but if I closed word and reopened the same document, It failed again. And this time it didn't ask for credential.
- checking on fiddler log, it did receive 401.
