The Del key is shared with the Backspace key and can be selected with the Fn key. If you want to press Ctrl+Alt+Del, it is not possible because the Fn activates Home on Ctrl and Mail on Alt. Otherwise, it is stated on the box that it is compatible with Windows.

I got it for use with the television.
In the positives:
- Small
- Relatively comfortable for typing
- Has LED for caps, numpad, and battery
- The trackpad also functions as a numpad
- Beautiful design
- Good range

In the negatives:
- Funny, but the trackpad doesn't work when the keyboard is resting on a surface. It works if you hold it in your hand (whatever)
- The construction doesn't seem so sturdy. It's all plastic and bends.
- I wouldn't recommend it for primary use on a computer in any case

I got it for a mini Mac.
- You can't drag & drop.
- When placed on a stable surface, the trackpad doesn't work. It needs to be hovering.
- The trackpad automatically locks frequently and you have to press a button to reactivate it.

I do not recommend it.
