I will reinforce the recommendation by (deleted user), I am running into this with a client now. They opted to go with installing SOLR on Linux but are struggling to support it. A couple of us on the project have some level of experience with Linux but most of the development team doesn't so that has been a struggle as well.
If you do have resources that will be able to support SOLR on Linux then there some added benefits, including some performance but I haven't yet add opportunity to quantify that on my project. For example the "bin/post" is a Unix shell script and there is not comparable windows command file like there is for "bin/solr". You can overcome this using the "post.jar".
