Maybe this will help you. After kicking around Windows 11 for a bit, I decided to get some work done and perform some Windows administration. I needed to install RSAT (remote server administration tools). In earlier versions of Windows 10, RSAT was a download.

I couldn't find RSAT for Win11 anywhere. I realized it is now a FOD (feature on demand).
To install RSAT on Windows 11
Click Start > Settings > Apps > Add an Optional Feature > View Features
IMO, The nice part about RSAT on Win11 is that you can cherry-pick the features you need/want.
In my case, I wanted AD, DHCP, DNS, and Group Policy management
tools. Check the RSAT tools you need, click NEXT > Install. After a
brief moment to download and install the tools, you're done.
If you're gung ho about powershell and/or which to automate the process, all of the RSAT tools can be installed via Powershell.
Launch Powershell as admin, execute commands below
