You cannot demote your root admin account.

I am not sure I understand your post, hope you can clear it up for me?
Windows 7 install, by default, gives you the option of naming the first user account, with Administrator privileges. The root Administrator account is disabled by default.
So if the OP (Original Poster) is using the default administrator account (and has not enabled the root administrator account to use), he can do what I just did: Change the first user account from administrator to standard user. Before I did that, I changed one of my standard user accounts to administrator so I can easily change it back.
So, yes, you can change the first user account from administrator to standard user. Go to Control Panel, to User Accounts, then Manage another account and change it to a standard user account.
Please let me know if this is not correct?
Cheers!
