Microsoft Windows functionality depends on hundreds if not thousands of files. The system is made of system files, information files, executable files and DLL files. Dynamic Link Library (DLL) files are crucial to the operation of the Operating system; some of the core fundamental files for the operation of Windows are DLL files. The advantage in DLL files is in their usability. A DLL file is a file with code and instructions within it; the file is made available to applications, developers and vendors. Problems can occur when files go missing due to incorrect removal of programs, or incompatibility with other files, though many things can cause these files to get damaged, corrupted or missing. Fortunately, Microsoft provides a way to scan a system for damaged or missing DLL files.

Go to "Start," "All Programs," "Accessories," right-click the "Command Prompt." Select "Run as administrator." The "Command Prompt Window" opens.

Type "sfc /scannow," and then press "Enter." The "System File Checker" program will scan your system, and then replace missing or damaged files from your system with the ones from your Windows disk.

Follow the instructions on the screen. When done, restart your computer.
