📋 About This Mod
Copy it to your AC4 install directory, where are your .exe files located, launch it, type "y" and press ENTER. It will be patched after it.
Pressing only Enter will give you info about current mode.
Patching again will revert all changes.
I think many of you will ask the question - does this work with the 240 FPS Patch ?
I hasten to make you happy - YES, it works
!!! WARNING !!!
If you have no experience in programming and do not quite understand what this program does - BACKUP YOUR ORIGINAL . EXE FILES BEFORE USING IT
!!! WARNING !!!
If something really went wrong (I don't know how this can happen) and your files were damaged - use file verification in steam/uplay - it will repair and re-download damaged files.
If it's still don't work (I don't know how this can happen) try use it with .exe file from 240 FPS Patch.
I tested both, original and 240fps patch .exe files, worked fine on both.

📊 Pros & Cons
✅ Pros
- Simple and effective solution for forcing windowed mode in AC4
- Reversible—you can switch back to fullscreen whenever you want
- Community-tested with 107 endorsements and over 7,000 downloads
⚠️ Cons
- Requires manual patching of the .exe, which may trigger antivirus or anti-cheat flags
- No detailed instructions or troubleshooting provided by the author
- Only works for windowed mode—no borderless or other display options
For AC4 players who need windowed mode for streaming, multitasking, or compatibility with overlays. Skip if you're fine with fullscreen or want more display options like borderless.
💡 Beginner Tips
- Back up your original AC4BF.exe before patching so you can restore it if needed.
- Run the patcher as administrator to ensure it can modify the game files.
- If your antivirus flags the patcher, add an exception—it modifies the .exe by design.
