OpenKM has many interesting features, but requires some configuration process to show its full potential.
Forum rules: Please, before asking something see the documentation wiki or use the search feature of the forum. And remember we don't have a crystal ball or mental readers, so if you post about an issue tell us which OpenKM are you using and also the browser and operating system version. For more info read How to Report Bugs Effectively.
After copy all files from linux to windows. Delete catalina.log file. Start openkm, and then try to login. Stop application and upload here ( into zip ) the catalina.log file ( I would like to see it ).
