Hi @Peeter Tiidemann ,
Welcome to Microsoft Q&A!
is it possible to find the list of all standalone updates for SQL SSIS, SSRS and SSAS Shared and Instance features?
Which SQL Server version do you used? Since SQL Server 2017, the Reporting Services has been separated from SQL Server installer. If you would like to upgrade SSRS to latest version, you could download from here. For SSAS and SSIS, they are still included in SQL Server installer. For more information, please refer to SQL Server installation guide.
