How to do a hard reset on Xbox one

To Hard reset your console

Press and hold the power button for 10 seconds. This will force the console to shut down. Once shut down remove the power cable from the rear of the console for 2-3 minutes. Reconnect then power up your console

You need to hold the button for 10 seconds for a
Powercycle

Another method is

• Go to the Home screen.
• Press the Menu button on the controller.
• Select Settings.
• Note You can say “Xbox, go to settings” from any screen, but you’ll need a controller once you’re on the
  Settings screen.

• Go to Power & startup.
• Select Turn Xbox Off.
• Select Yes. The console powers down.
• Turn your console back on by pressing the Xbox button on the console or the
  Xbox button on your controller.

I meant to clear the system cache, sorry my mistake. There has to be an easier and more reliable way to clear it.

I need help resetting everything will this still work, I want to reset profiles and setting's, everything so I can give it to someone else for there birthday is that possible?

Erm, it looks like we are both right, some sites call it a "hard reset" some call it a "hard restart" and some call it a "power cycle"

Either way, the end result is pretty much the same.

Admittedly Microsoft own support page describes it as a "power cycle" its just that I've seen it called a "hard reset" so many time on these forums I just assumed that's what it was called.
