If you need to delete the administrator account on your Windows 7 computer, there are a few different ways to go about it. The first way is to use the Control Panel. To open the Control Panel, click on the Start button and then click on Control Panel. Once the Control Panel opens, double-click on User Accounts and then double-click on Administrator account. On the General tab, under Account type, select Delete account and then click OK. The second way is to use a command prompt. To open a command prompt, click on Start button and then type cmd into the search box. Once Command Prompt opens, type in net user administrator /delete and press Enter. The third way is to use a software program called System Mechanic Professional Edition. System Mechanic Professional Edition can be downloaded from www.systemmechanicprofessionaledition.com/en-us/. After System Mechanic Professional Edition is installed, open it and click on Tools > Accounts > Administrator Account Removal Wizard > Next > Remove Account from Windows 7 (see Figure 1). ..
