RSAT on Windows 10 2004
We have search the Web and cannot install RSAT on this OS. nothing works. even after tearing holes in our security , we have fiddled and broken WSUS. and still we cannot get the RSAT tools installed.
We have the stand alone installer, we have tried the option feature approach. It simply will not install because we have a WSUS server. The end game over thats all folk, go back Windows 10 1809 so that you can work.
Not a big deal really, as long as machine has internet access you can bypass WSUS, either in the registry or (better option) use Martin Bengtsson's very handy PS script - see his blog post here: https://www.imab.dk/deploy-rsat-remote-server-administration-tools-for-windows-10-v2004-using-configmgr-and-powershell/
