I have an AdWords My Client Center (MCC) that I log into. I am the only one that can log into the MCC. Within the MCC, I have 3 linked Adwords Accounts. These are each separate, standalone AdWords accounts that were created by clients.During some testing I was doing, within my MCC, I clicked +Create Account and chose Adwords in order to add a new account to my MCC. Note: I am not linking an existing standalone account to my MCC. I am creating a new account within my MCC. I name this account Test Client 1.Now that I have created my new account, I want to delete it because I only made it as a test. If I go to Arrange Accounts > Unlink Account(s) I get the following error:This account must have at least one active user before you can unlink it.  Please invite a user to the account with Administrative Access or link  the account to another MCC before unlinking.So how exactly do I add an active user to this account, Test Client 1? When I click the account and go into the details of that account, I do not see anywhere in the interface where you can add a user to the account.If I go into my MCC preferences, here there is an Account Access page, which allows me to add a new user to the ENTIRE MCC account. But this gives the user access to the ENTIRE MCC. I don't want that. I just want to add a user to this one Test Client 1 account I made. There doesn't appear to be a way to give a user access only to a specific account within the MCC.Just for the heck of it, I went ahead and invited a new user to the MCC with full Administrative Access. Now I have my login and this other login (a dummy @gmail address I made) that can access my MCC. There still does not appear to be a way to add a user to the Test Client 1 account I made so I can unlink it.What am I missing here? How do I add a new active user to the Test Client 1 account?
How to unlink AdWords account created within My Client Center?

This is been asked in at least threads in the Google Adwords help forums.  1, 2, 3.The most helpful post in all of that is from sharepower:the only way to do it, it to create a new gmail account. Give this account admin access to Adwords. Only then will you be able to remove from MCC. Once removed from MCC, the Adwords account can be cancelled. I agree that its bizarre that Google does not allow removal of useless accounts in MCCHere are the instructions for cancelling an AdWords account.
