Post the brand, model number, installed operating system when asking a question.

Restore to a earlier date and time, the operating system set auto restore dates or you can set your own by going to start click help and support click system restore select the high lighted date click restore. This does not reinstall or do a system recovery to put the laptop back to factory or correct corrupt system files in fact I have found nothing system restore does to help with a problem after many years of using a computer running Windows.

Got to Microsoft support and type system restore into search to read more on the subject and how to do a restore.
