In Windows 10, File Explorer shows visible check boxes when you select a file. This makes file management easier with a touchscreen, but you might prefer a classic experience without those check boxes. You can disable them as follows.
When checked, the check boxes of items look like a small square ̵
This feature first appeared in Windows Vista and was enabled by default in Windows 8. You can even use item check boxes in Windows 7.
Select check boxes from the File Explorer ribbon
You can remove these check boxes from File Explorer itself.
First open File Explorer. To do this quickly, press Windows + E or click the folder icon in your taskbar if File Explorer is pinned there. You can also find File Explorer in your Start menu.
In the ribbon bar at the top of the File Explorer window, click the “View tab.
Locate "Item Check Boxes" in the View toolbar and click on it.
If the feature was enabled, the check mark in the box next to each file disappears. Once you select files, a check box is no longer displayed.
To enable the feature again, return to the toolbar view in Explorer and check the box next to "Item checkboxes" again. Click this option if you want to hide the check boxes and make them visible.
Alternative Method: Use the Folder Options Window
It is also possible to clear item check boxes using folder options in Explorer. To do this, open an Explorer window and click "View" on the toolbar. Click the "Options" button and you will see the Folder Options window.
Scroll through the list until you see "Use check boxes to select items". Uncheck and click Apply.
Then close the Folder Options window and the check boxes in File Explorer have disappeared. Enjoy!
