CustomWinBorders

A tiny Windows 11 app that hides or darkens the thin borders around all windows. No more bright lines cutting through your dark theme.

How To Use

1. Download CustomWinBorders.exe from this repo
2. Double-click to run it
3. That's it — borders are gone

A small icon appears in your system tray. Right-click it to:

• Toggle on/off
• Pick a color — Invisible, Black, or any custom color
• Run on Startup — On or Off
• Exit — puts everything back to normal

Double-click the tray icon to quickly toggle.

Requirements

• Windows 11 — no install or setup, just run the exe.
