I go into the user accounts section of the control panel to switch the way users logon and off. However, I get this message every time when I click on &quot;change the way users log on or off&quot; that reads <br />
&quot;A recently installed program has disavled the windows screen and fast user switching. To restore these features, you must uninstall the program. The following file name might help you identify the program that made the change:msGina.dll<br />
<br />
I deleted all the msgina.dll files, but the one that won't delete is the one located in sys32 folder? What is wrong here?

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
