------------------------------

I have three report servers but two of them have a problem.

If you want to use rskeymgmt you should start the CMD program with elevated privileges as shown:

Once CMD screen is displayed you can find the report servers as shown. I am using the l and i flags in rskeymgmt. The SQL Server Report Server 2012 PCATT has no problem, while the 2016 and 2017 SQL Server instances OHANA and SSRS are showing the same exception.

C:\>rskeymgmt -l -i PCATT   ---SQL Server 2012
HODENTEK9\PCATT - 879ea471-47cf-4386-b7f1-6eb213a5fff6
The command completed successfully

C:\>rskeymgmt -l -i OHANA     ---SQL Server 2016
The profile for the user is a temporary profile. (Exception from HRESULT: 0x80090024)

C:\>rskeymgmt -l -i SSRS      --default instance of SQL Server 2017
The profile for the user is a temporary profile. (Exception from HRESULT: 0x80090024)

The previous result was obtained using a Preview Build of OS that was not working well.

Recently 9/14/2018 there was an update to the OS and things have improved. Here are some new results for the same. 

Two of them are not displaying results, in one case the Database Engine is not running and in the other the Report Server is not running.
