How to resize caption buttons in Windows 10

In Windows 10, you can change the size of the caption buttons (minimize, maximize, close the window in the upper right corner of the screen) to smaller or larger.

Using larger caption buttons will also increase the height of the title bar.

This tutorial will show you how to change caption button size and title bar height in Windows 10.

This will not affect the caption buttons for the Store app and any modern user interface (e.g., Settings ).

2. Navigate to the key below in the left panel of the Registry Editor.

 HKEY_CURRENT_USERControl PanelDesktopWindowMetrics 

3. In the right panel of the WindowsMetrics key, double click on the CaptionHeight string value to modify it.

4. Enter a value between -120 (for smaller button sizes) to -1500 (for larger button sizes), depending on what you want to do and press OK.

Note : -330 is the default value.

Use the following formula to calculate the value to enter: -15 x the size you want (in pixels) .
