The benefit of resizing the three buttons is that the larger ones reduce the mouse travel distance, which can improve performance a little.

Even if you increase the text size in Settings > Accessibility > "Text Size," the three buttons will also become larger, but this method will change the size of the three buttons without changing the text size.

Please also refer to this if the size of the three buttons does not return to normal even after increasing the text size and then changing it back to normal.

How to change the size of the - ▢ ✕ icons in the top right corner of File Explorer

To change the size of the - ▢ ✕ buttons in the top right corner of Explorer, you need to edit the registry.

*Buttons in some apps will also become larger.

If you operate the registry incorrectly, it may cause problems such as the system being unable to start. Please make a backup in advance using system restore or similar, and proceed at your own risk.

To avoid panicking if your PC suddenly breaks down, it's a good idea to have a standard backup software to protect your important photos and data.

1. Press Windows key + R to open Run, type "regedit" and press Enter.

2. The Registry Editor will open, so open the following key:

HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics

3. With the "WindowMetrics" key selected, change the value data for "CaptionHeight" and "CaptionWidth" in the right column.

The default value data for both values ​​is "-330".

Precautions:

  • Enter the same number for the value data of "CaptionHeight" and "CaptionWidth".
  • Please enter a value between "-285" and "-500".

If you make the number too small, the icons for quick access in Explorer and the Registry Editor will also become small.Task tray (notification area)Some icons will be blurry.

Also, if you make the number too large, the size of the - ▢ ✕ will be too large and the display in Explorer will be distorted.

If you set it to "500", the three buttons become larger.

If you set it to "150" here, the quick access and bottom right icons are too small and hard to see.
