In Microsoft Windows operating systems, the "System32" folder contains files and information that make the computer, and any devices that are attached to it, function. This folder is so important to the health and performance of the operating system that in some cases, by default, the computer will request an administrative password just so a user can view the contents of the folder. Malicious software that infects a computer may be directed by their programmers to take over files in the "System32" folder, because taking over this folder is one of the keys to taking over the entire system.
Click on "Computer" or "My Computer." The desktop and "Start" menu icon will look like a computer.
Click on the main hard drive, which is normally designated as the "(C:)" drive.
Click on the "Windows" system folder.
Scroll down to the "System32" folder, and click on it to open it. You may need to provide an administrative password, which is only known by the computer's administrator and any other user to whom the administrator has given knowledge of the password. Once you're in the folder, you can view and modify anything in the folder, but be advised that you should work with these files only if you have the know-how to do so, without damaging the operating system.
