## WARP client for Windows (version 2025.8.779.0)

Oct 07, 2025

[Zero Trust WARP Client](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/)

A new GA release for the Windows WARP client is now available on the [stable releases downloads page](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/download-warp/).

This release contains significant fixes and improvements.

**Changes and improvements**

* [Proxy mode](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/warp-modes/#proxy-mode) has been enhanced for even faster resolution. Proxy mode now supports SOCKS4, SOCK5, and HTTP CONNECT over an L4 tunnel with custom congestion control optimizations instead of the previous L3 tunnel to Cloudflare's network. This has more than doubled Proxy mode throughput in lab speed testing, by an order of magnitude in some cases.

* The MASQUE protocol is now the only protocol that can use [Proxy mode](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/warp-modes/#proxy-mode). If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or switch to the MASQUE protocol. Otherwise, all devices matching the profile will lose connectivity.

**Known issues**

* For Windows 11 24H2 users, Microsoft has confirmed a regression that may lead to performance issues like mouse lag, audio cracking, or other slowdowns. Cloudflare recommends users experiencing these issues upgrade to a minimum [Windows 11 24H2 KB5062553](https://support.microsoft.com/en-us/topic/july-8-2025-kb5062553-os-build-26100-4652-523e69cb-051b-43c6-8376-6a76d6caeefd) or higher for resolution.

* Devices using WARP client 2025.4.929.0 and up may experience Local Domain Fallback failures if a fallback server has not been configured. To configure a fallback server, refer to [Route traffic to fallback server](https://developers.cloudflare.com/cloudflare-one/team-and-resources/devices/warp/configure-warp/route-traffic/local-domains/#route-traffic-to-fallback-server).

* Devices with KB5055523 installed may receive a warning about `Win32/ClickFix.ABA` being present in the installer. To resolve this false positive, update Microsoft Security Intelligence to [version 1.429.19.0](https://www.microsoft.com/en-us/wdsi/definitions/antimalware-definition-release-notes?requestVersion=1.429.19.0) or later.

* DNS resolution may be broken when the following conditions are all true:

  * WARP is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
  * A custom DNS server address is configured on the primary network adapter.
  * The custom DNS server address on the primary network adapter is changed while WARP is connected.

  To work around this issue, reconnect the WARP client by toggling off and back on.
