How can I change a standard user back to an administrator?
I was told to change myself to a standard user from an administrator in order to be able to perform the task I was trying to perform. I completed the change and now I cannot change it back.
I do have another administrator but cannot sign-in to that admin.
How can I complete this operation?
I have asked this question before but the solution did not work. There was another solution but cannot get back to the person who said "If this does not work, there is one more solution".
