I'm certain that, that seemed clear and concise to you as you were typing, but I am a bit confused.
My first suggestion is that you give it some time and a couple reboots just to see if it manages to self sort itself out.
What form did the "repair install" take?
Did you perform an in-place upgrade repair and install Windows 10 overtop itself or did you employ another method?
IF I understand correctly and that is in doubt.....
Prior to the repair (whatever form that may have taken) you had a User Name for the sake of specificity let's call him JohnSmith.
NOW.... you are logging in as that user (JohnSmith) but the desktop you are seeing is not the desktop that you saw, using the same user name prior to the repair???
BUT
That user profile folder exists in C:\Users\JohnSmith along with all associated subfolders and files (Desktop, Documents, Music, etc., etc.)
First question....
IS there a second profile folder in C:\Users?
With another name or perhaps a suffix such as JohnSmith.000
OR
Any other unfamilar user profile folder?
Often you can associate date and time stamps to determine which one is currently being used.
