My chosen way (I am a dedicated customiser!!!) is to do into
C:\ProgramData\Microsoft\Windows\Start Menu\Programs
and create folders in there, and then move individual items into each folder.
I run permanently as the Global Administrator, but as a user/Admin. you may also find you need to open
C:\Users\username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs
and copy (D= NOT Move!) some of the user items which do not exist in program data, over to there.
here is an example of how my start menu looks.
