Other Configuration Manager-related features and issues
Hi, @Bojan Zivkovic
Thank you for posting in Microsoft Q&A forum.
Install CU for SQL Server Express is similar to install CU for SQL Server.
We can start the CU update installation, it will check files in use that might affect the installation, such as SQL Server management studio, close them and finish the CU installation.
You may refer to this article for more details:
