Amusing post; made me smile, but I understand your frustration.
In spite of the fact you think otherwise, you're not logged in as Administrator. There is such an account, but it's disabled by default. To enable it, open a command prompt (right click the link and choose "Run As Administrator" first), then at the prompt, type: net user administrator /active:yes
and hit Enter.
You should get a message that the command was successful. Next, type: EXIT
to close the prompt and then reboot. When the system boots to the logon screen, you'll see "Administrator" as an option. It doesn't have a password by default, so just hit Enter to boot to the desktop.
Obviously (I hope
), by using the built in Admin account all the time, you're putting the machine at serious risk because if system is compromised, then the attacker will have unrestricted access to everything. He can even password protect the Administrator account so that you'll be unable to access it which will mean a reformat thereby wiping everything on the machine.
To preempt that, you need to configure a secure password comprising of at least 18 characters, both upper and lowercase letters, numerals and special characters i.e. those located above the numerical keys on the top row. You might also want to consider renaming that account as an additional security measure, illustrated instructions here: How to Rename the Windows 7 Built-in Administrator Account
In answer to your other query, you can as Administrator, delete your existing account and then recreate it under another name.
