I use this bash function:
# isadmin - is shell a regular user or admin user
function isadmin()
{
$(cygpath -u 'C:\Windows\System32\net.exe') session > /dev/null 2>&1
if [ $? -eq 0 ]; then echo "admin"
else echo "user"; fi
}
I imagine any other Windows app that needs admin permissions would work.
I use this to change the color of the prompt ($PS1) for the admin user to red.

"Ich sollte meine Frage konkretisieren:" Does the Cygwin implementation of pathconf() support query data of the underlying filesystem based on data from the kernel, as UNIX does? So pathconf() returns different values for NTFS, ReFS, or Windows builtin NFSv3? I am asking, because as far as I know the Linux implementation is not a syscall, and instead glibc guesses values based on builtin static data, and whatever fstatfs() has to offer. Compared to that UNIX (Solaris, AIX, HPUX, ...) have pathconf() as a syscall, and actually ask the filesystem itself.

In earlier Windows versions, you could also check for group 547 which
