In Windows 7, the Administrator account is opened or disabled in the Home Edition. I did not remember the specific reason. I opened the Administrator account in Windows 7 (it may be that a program requires special permissions ). After each boot, two accounts will be selected, one is Administrator and the other is my original normal account. Because no record is made, I do not remember how I opened the Administrator account, so I naturally do not know how to close it. Today, I can't help but wait until I start windows, and then click an account to start windows. After searching, I found that there were two simple commands: Enable the Administrator account: 1net user administrator/active: yes, and disable the Administrator account: 1net user administrator/active: no, but there is a premise. Run the cmd program as an administrator and then execute the above command in cmd.
