WireGuard makes new Windows release following Microsoft signing resolution

Summary

[ANNOUNCE] WireGuardNT v0.11 and WireGuard for Windows v0.6 Released Jason A. Donenfeld Jason at zx2c4.com Fri Apr 10 14:20:51 UTC 2026 Hey folks, I generally don't send announcement emails for the Windows software, because the built-in updater takes care of notifying the relevant users. But because this hasn't been updated in so long, and because of recent news articles, I thought it'd be a good idea to notify the list. After a lot of hardwork, we've released an updated Windows client, both the low level kernel driver and api harness, called WireGuardNT, and the higher level management software, command line utilities, and UI, called WireGuard for Windows. There are some new features -- such as support for removing individual allowed IPs without dropping packets (as was added already to Linux and FreeBSD) and setting very low MTUs on IPv4 connections -- but the main improvement is lots of accumulated bug fixes, performance improvements, and above all, immense code streamlining due to ratcheting forward our minimum supported Windows version [1]. These projects are now built in a much more solid foundation, without having to maintain decades of compatibility hacks and alternative codepaths, and bizarre logic, and dynamic dispatching, and all manner of crust. There have also been large toolchain updates -- the EWDK version used for the driver, the Clang/LLVM/MingW version used for the userspace tooling, the Go version used for the main UI, the EV certificate and signing infrastructure -- which all together should amount to better performance and more modern code. But, as it's our first Windows release in a long while, please test and let me know how it goes. Hopefully there are no regressions, and we've tested this quite a bit -- including on Windows 10 1507 Build 10240, the most ancient Windows that we support which Microsoft does not anymore -- but you never know. So feel free to write me as needed. As always, the built-in updater should be prompting users to click ...
