I accidentally started a computer which is pre-installed with Windows. A GUI with the title "Configure Windows" started a procedure which lets the user enter language, user name and other information in order to create a working windows installation.
I would like to abort this procedure, and restore the computer to the state it was in before I switched in on. How can I do this?
The GUI does not seem to offer a way to abort. There are no "Cancel" or "Abort" buttons.
Can I just switch the computer off (by holding down the power button) in the middle of this procedure? Would the computer start and be healthy again?
