System Restore is a feature which allows users to restore system information such as files, registry, or list of installed programs. System Restore is very useful if you experience problems with your computer related to your operating system. If that is the case you can simply use System Restore, and everything should be back to normal. It is recommended to do System Restore before installing any programs, especially those which appear to be dangerous or not compatible with your operating system. If you will not restore your system, the only other solution would be format which is time consuming, and there is a danger of losing any data on disc “C”. System Restore might not fix all of the problems, but it is an extremely useful feature.
