Double-clicking an item in Windows 10 opens it by default.
To open an item in Windows 10 with a single click, follow these steps:
The “General” tab, in the “Click items as follows” section, displays “Single-click to open an item (point to select).” Click it.
Under that, you will find two options:
- Underline icon titles consistent with my browser – This option will always show the underline in the item title.
- Underline icon titles only when I point at them – If you choose this option, you will see an underline in the item title when you hover your mouse over it.
Pick out the one you want from the two options above and click “OK.”
From now on, you can open an item with a single click.
If you want to go back to default, then open File Explorer Options, select “Double-click to open an item (single-click to select),” and then click the “Ok” button at the bottom.
