System Restore
System Restore is a windows feature that allows for backup of system files.
In case of a system crash, virus, or stupid mistake these files can be used for
recovery to a prior point.
This feature is NOT turned on by default and must be manually
setup/started.
The recommended drive space allocated is 10GB.
