Then if anything goes wrong, like if you accidentally delete a monitored program file or a file becomes corrupted, you can simply turn back the clock and revert to a set of previous satisfactory settings. All this without losing any work, including emails, favourites and browsing history. This is because System Restore leaves your files as they are, and only undoes system changes.
System Restore is not a program uninstaller. If you are using Restore because you just installed a program that causes problems or you just don't like it be sure to use that programs uninstaller first. Go to Control Panel/Add or Remove Programs to do so. This will assure removing all traces of the offending program.
Note:If you can't get Windows started normally to get to System Restore follow these instructions
When your computer first starts to boot up right after it shows the drives installed press and hold the F8 key. This will show you the Boot menu with restore options. Use the arrow keys to highlight "Last Known Good Configuration" (your most recent settings that worked) and press Enter.
