How do I delete Windows 8.1 my own account lock screen photo
I have a fairly new ASUS laptop with Windows 8.1 and have been playing around with the settings etc. and have a question regarding the lock screen.
I have personalized the lock screen with my own picture but have decided that I don't like it and would just prefer to use one of the default pictures, but there doesn't seem to be anyway of deleting the picture I have added.
I've tried searching for the picture on the laptop but have had no success finding it.
Can someone please advise me as to how delete this picture?
Many thanks,
Mike
