In the win10 system, the window title bar and scroll bar width are adjusted

. 1. First, we need to return to the traditional desktop position of the win10 system. After that, we can press the win+R shortcut key on the win10 computer keyboard to open the running window of the computer. After that, we type regedit in the open running window and click Enter. This will open the registry editor window of the win10 system.
2. In the open registry editor window, we expand HKEY_CURRENT_USERControl PanelDesktopWindowMetrics in the left menu, then find the CaptionHeight string value on the right side, which represents the height of the window title bar, and its value is calculated as: -15* desired height (pixels). For example, if you want the window title bar height to be 18, then its value should be -15*18=-270.
And for the setting of the scroll bar width, its corresponding registry key value is ScrollWidth, which is calculated in the same way as CaptionHeight.
