Creating system restore points
A system restore point is a snapshot of certain hard drive contents saved by Windows System Restore at a
specific time. A restore point contains information such as registry settings that Windows uses. Restoring to
a previous restore point allows you to reverse changes that have been made to the system since the restore
point was created.
Restoring to an earlier system restore point does not affect data files saved or emails created since the last
restore point, but it does affect software you may have installed.
For example, if you download a photo from a digital camera and then restore the computer to the state it was
on the previous day, the photo remains on the computer.
However, if you install photo viewing software and then restore your computer to the state it was on the
previous day, the software will be uninstalled, and you won't be able to use it.

Backing up system and personal information
Your computer stores information that is important to you, such as files, emails, and photos, and you will
want to keep that information even if you download a virus or the system stops working properly. How
completely you are able to recover your files depends on how recent your backup is. As you add new
software and data files, you should create backups on a regular basis.
