Write a tutorial regrading windows administration and employee account permission

Hi, This project is for experienced windows system administrator. The administrator have to write a tutorial about, how can we create windows system accounts with different permissions as describe below....... 1. We are a company. Our company has many windows computers. Those windows computers are used by different employees. 2. A computer will have only one administrator account. This administrator will have highest privileges to the system. Administrator can install and uninstall software from the system. Administrator can add and remove employee(guest) account to the system. Administrator can create any number of guest account with desired name, username and password. 3. Employee will login to the system using their own username and password. They cannot see files and programs of another employee. That is they can only see files and programs those are allowed to show them. 4. Employee can not install or uninstall program or software in the system. They cannot see files of other employees. 5. You have to write a good tutorial with screenshots and commands those are needed. So we can easily implement in our system by reading your tutorial. Regards, ALSOFT
