Windows 2007? You mean Windows 7?

With an admin install on Windows 10 and Windows 7, both 64bit, I got
the intended permissions: read and execute for 'users' and
'authnticated users, and full permissions for administrators.

Maybe some funny permissions have been inherited from C:\ or from
C:\texlive?

What is the output of:

icacls C:\texlive

icacls C:\texlive\2020\texmf-dist

icacls C:\texlive\texmf-local
