We all know how Windows computers slow down over time. This can be caused by programs that add themselves to the boot process, temporary files, and disk fragmentation. Microsoft provides a number of tools to help, including settings for updates that are important for security and safety. This course is designed for students who want to understand a little more about the operating system and the tools that are provided to optimize performance and security. File cleanup, defragmenting, auto-updating, setting restore points, and general maintenance are all covered in this class.
