We have automatic updates of .NET Core 3.1 and .NET 6 enabled in our Enterprise, using WSUS with Configuration Manager as the deployment tool.

We are experiencing an issue where the updates leave behind older versions of the SDKs and Runtimes installed.

Programs and Features in Control Panel only show the latest version of the SDK, but registry entries in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall are left behind as well as the files.
