Hi, we have a mix of Windows 2012/2016/2019/2022 environment where all our servers are located in the same OU. We want to install Windows updates manually and we have no GPO settings configured for Windows updates.
All of a sudden our 2016 servers had "Check for updates" or "Install updates" buttons greyed out, while our other servers on other Windows Server versions, all located in same OU, can install updates normally from GUI. After examining a bit further, it seems like I am able to install updates just fine using sconfig in powershell (option 6 - install updates). I am logged in as domain administrator.
Besides not being able to install updates from GUI I attempted to uninstall an app in the "modern interface" on a 2016 server (settings - system - apps & features), and I am getting the following error:
Uninstalling the same app through old interface from Control Panel works just fine.
We've always ran windows updates manually and I am the only admin who deal with GPOs etc. I've never configured a GPO for windows updates and I've triplechecked GPRESULT (nothing related to windows updates). So despite the GUI looking like this might be controlled by a GPO: If it was, I wouldn't be able to install the updates using sconfig either.
So to me, this looks like a 2016 GUI bug of some kind? Anyone seem anything simillar? Ideas on how to troubleshoot? All input much appreciated.
