I never used optimus on windows, so I can't help. I would highly recommand that you install Theano 1.0rc1 after you have made the cuda sample run. See this page: https://github.com/Theano/Theano/wiki/Converting-to-the-new-gpu-back-end(gpuarray )
On linux, for optimus to work, you need to enable it on the command line: optirun python ... You will need to find how to do this on windows. If you find, tell us. It could help other people.
