Can someone please tell me where this button is on my computer?

they are 3 separate keys that you press at the same time

The delete button should be somewhere on the top of the keyboard (otherwise known as above the backspace key. Otherwise it may be on a 2x3 key section with delete on it.

Look at your key board. You'll find a Ctrl button. Alt button. and delete button. You'll press Ctrl button first, hold it down with one finger. Will holding Ctrl button find Alt button and press and hold it down and then find delete button and hold it down. You'll hold all them down together. So just hold down Ctrl , Alt and delete down altogether. You'll press the three buttons at the same time in orded from Ctrl then alt then delete. Hope I helped

Ctrl/Alt/Delete is an abbreviation for a keyboard shortcut. It means to press and hold the Ctrl key while pressing the Alt and Delete keys at the same time. The Ctrl key is next to the Windows key to the left of the space bar, the Alt key is directly to the left of the space bar, and the Delete key is above the arrow keys.
