Explanation:
Restore System to a Previous State Using Restore Point
Restoring your Windows operating system to a previous state is nothing new, but this feature can be very
handy and time saving. For example, if you installed a new application or driver and your system starts to
behave abnormally, or if your computer is infected by a virus from one unintentional mouse click on a link,
wherever the case may be, you may want to go back to a previous state, say yesterday. You can refresh or
reset your system, but system restore is your best bet for this kind of scenarios.
