if you have some knowledge of OpenPGP and the command line,
I suggest to try a lot of the operations on the command line
on Windows to seperate the problem.

Usually "gpg2 --version" will give you an idea what the crypto backend can do.

The Windows and GNU/Linux variants of GnuPG are basically the same
so they should have the same capabilities.

True, the advanced manual does not cover this.
The gui frontends are mainly for the daily usage operations and mainstream
configuration options. If you would like to have something more out of the
ordinary, you need to consult the GnuPG documentation directly.
Which version of Gpg4win did you try? The 1.9.x?
If not, try it. I thought we can do DSA2 and there is a selection of key
length in the wizard for generating a new key.
