"Doesn't work" is a little vague. Can you give us an example? Then
we could say if it works or not.
To pre-emptively respond, -f is as the documentation says:
-f FILE, --file=FILE
Obtain patterns from FILE, one per line. The empty file con-
tains zero patterns, and therefore matches nothing.
Therefore an example (using GNU syntax) would be:
$ echo oo > patternfile
$ echo foo > datafile
$ grep -f patternfile datafile
foo
You would need to adapt that for your Cygwin system but I assume you
know it better than I do since I do not know it very well.
