from where is kubectl coming from ?
In cygwin I found only a kubectl.py in the ansible package
It's from here:
https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-windows
.
so it is NOT a cygwin program.
If the warning is coming about curl, it is likely
that using from cygwin you are using the cygwin curl
and from CMD the windows one
$ which -a curl
/usr/bin/curl

the support Forum https://discuss.kubernetes.io/
