+# Windows notification group

+**Github Label:** [O-Windows]

+[O-Windows]: https://github.com/rust-lang/rust/labels/O-Windows
+
+This list will be used to ask for help both in diagnosing and testing
+Windows-related issues as well as suggestions on how to resolve
+interesting questions regarding our Windows support.
+
+The group also has an associated Zulip stream (`#t-compiler/windows`)
+where people can go to pose questions and discuss Windows-specific
+topics.
+
+To get a better idea for what the group will do, here are some
+examples of the kinds of questions where we would have reached out to
+the group for advice in determining the best course of action:
+
+* Which versions of MinGW should we support?
+* Should we remove the legacy InnoSetup GUI installer? [#72569]
+* What names should we use for static libraries on Windows? [#29520] 
+
+So, if you are interested in participating, please sign up for the
+Windows group! To do so, you open a PR against the [rust-lang/team]
+repository. Just [follow this example][eg], but change the username to
+your own!
