Introduction
Sometimes, SharePoint Administrators face this issue while performing a SharePoint patch. Even after successfully installing the SharePoint patch file, the config wizard shows that the patch is still missing on the server. On checking the Manage Servers On-Farm page in Central Admin, it still shows the status of the server as 'Upgrade Required'. Also, on the product/patch installation page, the user can see many updates as missing/required.
Solution
The solution to this issue is simple. You just need to run below command on that server:
Get-SPProduct -Local
After this, refresh the Manage Servers on the farm page and you will see the updated status.
