Windows users can unzip WindTerm_2.x.x_Windows_Portable.zip and double‑click WindTerm.exe to start.

Settings and Usage

The author’s blog ( https://kingtoolbox.github.io/ ) details many features; the following are common configuration tips.

Set terminal font by editing the theme file global\themes\dige-black\scheme.theme and changing the fontFamily property.

{
    "name": "text.default",
    "style": {
        "foreground": "#F8F8F2",
        "background": "#1c1c1c",
        "fontFamily": "Microsoft-Yahei-Mono,Consolas Yahei Hybrid,Roboto Mono, Fira Code Retina, Lucida Sans Typewriter, Lucida Console, Monoca",
        "fontSize": 11
    }
}

Modify the fontFamily value to change the font.

Adjust window opacity via View → Window Opacity → Custom Opacity.

Synchronize sessions across multiple computers by syncing the profiles folder with a cloud drive.

Disable the default 30‑minute auto‑lock screen by setting application.lockScreenTimeout to 0 or a negative value in global\wind.config and restarting the client.

Add frequently used commands as shortcut commands through the gear button in the lower‑right corner.

Configure a jump host by editing Session - SSH - Proxy - Jump Server 1 in the session settings.

Performance

Because WindTerm is written in C, its performance is strong; memory usage is around 70 MB, far lower than the 2 GB consumed by FinalShell.

Conclusion

WindTerm offers a rich feature set that fully satisfies the needs of operations staff and can replace tools like Xshell or FinalShell, though some options still require manual configuration file edits. Multi‑language support is planned for a future release.
