WUG (Windows User Group) Czech Republic is a civic association that brings together IT professionals and others interested in Microsoft Windows and related technologies. Its mission is to foster knowledge-sharing and professional connections through lectures, technical seminars, conferences, educational events, and regular meetups for members and the wider public. Attendance at WUG lectures is free, and people interested in speaking can contact their local branch organizers.

WUG operates branches in Brno, Hradec Králové, Ostrava, Plzeň, Prague, and Zlín. Its program covers a broad range of technology topics, including Microsoft Fabric, software development, containers, cybersecurity, artificial intelligence, and cloud and infrastructure tools. The organization also shares recordings of past talks and event photos, giving visitors access to learning materials beyond in-person meetings. Upcoming events are listed by city and date, while the site provides information about speakers, past activities, registration, and ways to get in touch. By combining practical technical presentations with opportunities to meet fellow professionals, WUG supports continued learning and community engagement across the Czech Republic.
