Restoring the PC to factory default settings can help remedy these issues before they cause damage to the computer's hardware or compromise the personal information of the user.

Old computers tend to collect many residual files from installing, running and even uninstalling unnecessary programs. Over time this slows the computer down and leaves less hard drive space for important applications and files.

Rebooting the computer, reinstalling necessary programs and reorganizing files creates a better work flow.
