You should not work with administrative rights by default. In all modern operating systems, the user accounts can be assigned different rights. Unlimited access to all functions of the operating system is given to user accounts of the category "administrator" or "root". The rights are restricted for "user" or "restricted" accounts.
Administrator rights are required to make or change configurations. Working with administrator rights makes it possible for many malicious programs to be fully exploited, or a successful attacker automatically has administrative rights.

You should disable or delete unused user accounts.


If you are running Windows with limited privileges, you may be able to access administrative privileges if necessary

1. by right-click on the executable file, select "run as", and enter the log-in data of the administrator.

2. by opening the command line as follows: %SYSTEMROOT%\system32\runas.exe /user:[LOGINNAME DES ADMINISTRATORS] "%SYSTEMROOT%\system32\CMD.EXE"

3. by opening the Internet Explorer with the following command to use him as file browser (Explorer): %SYSTEMROOT%\system32\runas.exe /profile /user:[LOGINNAME DES ADMINISTRATORS] "%PROGRAMFILES%\Internet Explorer\IEXPLORE.EXE

(A direct second instance of the explorer can not be started on the system).
After entering the command, the administrator password is requested.
Open Internet Explorer with the specified command, you can enter a drive letter in the address bar and get the representation from the Explorer. A restriction must be observed: Internet Explorer does not recognize any changes made to the file system correctly. Place especially a new folder or delete a folder, this change will not be visible. The change in Internet Explorer is not displayed until the F5 function key is pressed.
In order to be able to work with the command, you can create a shortcut on the desktop by typing the command as a link target when you create the shortcut. The [LOGINNAME DES ADMINISTRATORS] has to be modified.
