If you press F1 to display Help while the OOBE Wizard is running, and then press the ALT key, the OOBE Wizard stops responding to keyboard input.
This behavior occurs because focus has been removed from the OOBE Wizard.
To regain focus, use any of the following:
- Press ALT+TAB.
- Use your mouse to click in a screen element.
- Press the question mark (?) and press Hide.
