This modification helps you quickly identify and interact with the scrollbars, especially on high-resolution displays where standard scrollbars might appear too small.
You adjust scrollbar size in Windows 11 by modifying registry settings. Open Registry Editor, navigate to 🗝️HKEY_CURRENT_USERControl PanelDesktopWindowMetrics, and change ScrollHeight and ScrollWidth values. Restart Windows Explorer for the changes to take effect.
