How to uninstall a SQL Server 2016 Cumulative Update
27 August,2019 by Tom Collins
Question: A server experienced a few problems after the installation of a SQL Server 2016 Cumulative Update. As part of the troubleshooting process, I'd like to rollback the cumulative update and rule out any issues related to the Cumulative update. How can I uninstall the cumulative update?
Answer: Uninstalling the cumulative update in SQL Server 2016 is straightforward. I've copied an pasted these 3 steps straight from the Microsoft website
- In Control Panel, select View installed updates under Programs and Features.
- Locate the entry that corresponds to this cumulative update package under Microsoft SQL Server 2016.
- Press and hold (or right-click) the entry, and then select Uninstall.
You'll notice in the example , the description mentions HotFix - which you may find confusing , but focus on the KB number
If you're interested in using Powershell - you can try these commands to view the information
To view the hotfixes on a server , along with Installed Date , Description , HotFixID , InstalledBY etc , run this command on the sever
