How to Install Happ on Windows and Get Connected
Happ for Windows is a desktop client built on Xray-core that connects to a server using a key from the Telegram bot. Here's the setup, step by step, from downloading the file to picking a fast server.
Step 1. Download the installer
Open the Windows download page and grab the installer. Once it's downloaded, run it and complete the standard installation on your computer.
Step 2. Request an access key from the bot
Open the service's Telegram bot and get an access key or subscription link. Copy it right away — you'll need it as soon as the app launches for the first time.
Step 3. Paste the key into the app
Launch Happ, open the add-subscription section, and paste the link from your clipboard. The app processes it automatically and adds a new connection profile with a list of servers.
Step 4. Pick a server and turn the VPN on
Once the subscription is added, open the server list — for low-latency gaming and steady streaming, the geographically closest server is usually the best pick. Click connect; on first launch Windows may show a system prompt to install a VPN driver, which you'll need to approve.
Advanced options for power users
The Windows client also supports more granular controls: split tunneling, where part of your traffic goes directly and part through the VPN, plus support for adding custom configurations.
Frequently asked questions

Can I try Happ on Windows for free?
