Uninstall CU19 for our SQL 2019 (on Windows 2022).

[Berch1108]

We recently installed CU19 for our SQL 2019 (on Windows 2022). When we were trying uninstall CU19, it is prompting for the installation media. I am afraid that will not make any harm to the SQL server. I haven't experienced this type of behaviour when uninstalling patches.
Appreciate if you could advise.

@Berch1108 , why do you want to uninstall the CU, sounds it don't make sense?

If you need installation media, download the free available Evaluation Edition at SQL Server 2019 | Eval Center (microsoft.com)

Thanks.
I was just testing the rollback before I going to apply in production.
I got the below response.
