Enable / Activate Administrator Account?

I tried to enable/activate my administrator account by following these steps:

1. Open the Local Users and Groups manager.

2. In the left pane, click on the Users folder.

3. In the middle pane, right click on Administrator and click on Properties.

4. To Enable the Buit-in Administrator Account Uncheck the Account is disabled box.after creating enabling the administrator account I just rename it to my interested nickname and I set a password for that.But I still have to run some programs as "Run as Administrator" while I am in administrator account!. I can also see and access to all of stored file and folders (which I saved as Administrator in my document) when I log in as a standard user!I also enable / activate Hidden Administrator Account by this way:

1. Type "secpol.msc" in RUN dialog box or Startmenu search box, it'll open "Local Security Policy" window.

2. Goto "Local Policies -> Security Options".

3. Double-click on first option "Accounts: Administrator account status" and select "Enabled" and apply it.
