DPI Unaware is a tool that helps users configure Windows applications as "DPI Unaware," allowing Windows to handle scaling on high-DPI displays. This setting is particularly useful for legacy applications that are not optimized for high-resolution displays.

On high-resolution displays, some applications may appear too small or have disproportionate UI elements. DPI Unaware solves this issue by modifying the Windows registry to force these applications to use Windows' DPI management.
